Access Point Mounting for Warehouses and Open Ceilings Part #2 - Mounts

In part one we discussed some environments that make it difficult to deploy wireless such as warehouses, factories and open ceiling offices. One of the major reasons that these environments are difficult to deploy in is that we need to mount an Access Point where no mounting surface exists. In part one, we talked about some of the hardware that we can use to hang an Access Point to help “create” a mounting surface. In this post we’re going to go over some of the incredible mounting solutions that vendors have come up with to further help finish off the mount solution. Please note this is not an exhaustive list of what is available. These are just a few options from two of my favorite providers.

AccelTex Universal AP All-Thread Drop Mount (ATS-DRPMNT-UNIV1)

This is a great simple mount for areas where you need to deploy an AP with built in, or directly-attached antennas. It’s made to simply mount from threaded rod. Meaning that you can hang it at any height necessary to get the AP below obstructions. Hanging from the threaded rod is simple. First determine the height that you will want the AP to be mounted from, and situate your threaded rod accordingly. The first post in this again has a couple of different mounting options to do this with. Once the threaded rod is hung, you will want to thread on a nut and thread it a little above where the mount will end up to give you some room to work when getting the mount in place. Then slide the mount onto the threaded rod through the hole in the top of the mount, but be sure to put a washer in between the nut and the mount itself. Then underneath you will place a washer and another nut. Use these to get the mount positioned at the correct height. Once the mount is correctly situated height-wise, you can tighten the nut on the top to secure the mount in place. Then its time to attach the Access Point. If it can be avoided, I would certainly wait to attach the Access Point until the mount is in place so that you don't drop the Access Point off of the mount while jostling the mount into position. Remember these mounts are normally going up fairly high. No reason to have a drop test of an expensive Access Point from that height.

When it comes to actually attaching the Access Point, you have the four keyhole slots for Cisco Access Point feet. For Aruba Access Points, you just use the normal T-Bar bracket which attaches to the center cross-bar that you can see on the mount.

Quick note - Sorry, I didn't have my Aruba 205 on hand when I took these pictures. So you'll just have to take my word for it that it works.

AccelTex states that these are compatible with a number of other manufacturers other than Cisco and Aruba. However I had trouble with both Aerohive and Ruckus T-Bar mounts. The mounting section just wasn't wide enough. I've spoken to AccelTex about this and they are going to look into it. So if they ever come out with a 2nd generation of these and it has a wider mounting surface that's compatible with more Access Points, please send all the credit and accolades my way.

One thing to note about this mount is that it's fairly low profile (only 4.3" tall without the AP) and unobtrusive. The fact that its painted will help it blend in if installed in many office environments as well. As long as threaded rod will also blend in with your office decor. I can also see this being utilized in large box stores or supermarkets. 

AccelTex AP And Omni Or Patch Antenna All-Thread Drop Mount (ATS-DRPMNT-UNIV1-OOOP)

This is the previous mounts external antenna brother. It uses the same mounting method as the other threaded rod mount. However this one is built for AP's utilizing external antennas. The Access Point gets mounted on the "top-side" facing towards the ceiling on this one, with the antenna being installed on bottom of the opposite side of the mount. This helps keep the antenna cables on the top of the mounting bracket and above any of the antenna propagation. It also just makes it look that much neater. 

Pro-Tip: When installing the AP using one of these mounts. Get the mount in place as described for the mount above. But get the Access Point fully cabled with its antenna and ethernet cabling before attaching it to the mount. When the Access Point is attached to the mount there is very little room to slide an ethernet cable in, or to get the antenna cabling attached under the arm that the threaded rod attaches to. 

Ventev Hanging Conduit AP Mount (TW-HC-MNT)

Bottom is facing up

This is another great hanging solution for Access Points with internal or directly-attached antennas. Ventev designed this mount  to be hung from conduit rather than threaded rod. Which in many places you may have all of your ethernet drops run in conduit. Plus, it means that your hanging method and cable management are all in one. With no visible cabling to the Access Point, this makes for a very clean deployment. 

There are a number of small things Ventev did with the design of this mount that I really like. As we go through reviewing the mount I'll touch upon these. 

Above you can see the mounting surface of the mount, where the Access Point will actually be attached. First thing you might notice is what looks like a plug or button sticking up from the mounting surface. This is one of those small design features that I talked about that make this such a slick mount. We'll get into its use in a minute.

Opening the mount uses another one of those really nice small touches. To open it you simple unscrew the screw you can see in the front. But the well designed part of this is that its a self-capturing screw (my term) that allows you to fully unscrew it to release the hinged part of the mount, but the screw stays attached to the mount itself. This means that while you are up on the ladder or scissor lift installing the mount, you can't lose the screw! Seriously, such a small thing, but a really nice design feature.

Once we crack open the mount you will see the handle on that's attached to that button we spoke about earlier. You might be able to tell that that handle looks like its designed to swivel that button. 

To mount a Cisco Access Point, you'll simply use the keyhole slots found on the bottom of the mount. Once in place however, we get to see where that button comes into play. 

It's actually a locking mechanism to keep the foot retained within the keyhole slot! All you do is simply lift on the handle, and swing the button over to where it needs to go and it helps retain the foot.That way if the mount is bumped in any way, the Access Point will stay in place. 

Mount on AP2702I

On the bottom view of the mount you may have noticed there were a couple of other slots. One rectangular slot for cabling the Access Point. The remaining two slots that have indents facing each other are for mounting Aruba Access Points. Whats nice about this method is that you don't need the T-Bar rail attachments. You actually use the built in "catches" on the Aruba Access points that are normally used to hold the T-Bar mounting bracket to the Access Point. This way you don't need any extra items to mount the Access Point. Also, since you are using attachment points built onto the Access Point, it makes for an even lower profile attachment. Ventev also integrated that button here as well. On the bottom of Aruba Access Points is a small indent that the T-Bar attachment usually pivots on. Ventev uses this hole to keep Aruba Access Points from moving around on the mount. Pretty genius!

Although not everything is perfect with these mounts. As you can see below, the mount covers the ports on the AP205. I don't have a newer Aruba Access Point on hand to determine whether the cabling slot will work with those. Their documentation seems to indicate that it will. But bear in mind that it will not work with Access Points with the form factor of a AP205. 

We've looked at the bottom of the mount, and at the inside, so now lets take a look at the top.

You'll notice that there is the one large hole, this is so you can slide 3/4" conduit in, and then hang the mount from the conduit using a conduit nut. If I could make a suggestion for the next design iteration of these, it would be to put an extra hole on the top of these. That way, you could also use threaded rod stuck through the conduit hole and secured using large washers. The ethernet link would then go through this proposed second hole. I guess one could always be added onsite if that's the route that you wanted to go.

Ventev I-Beam Low Profile Mount (TW-IBEAM-MNT-AP)

Looking at the bottom, or, in other words the surface the Access Point would mount to.
This is a great mount for warehouses and manufacturing facilities with I-Beam construction. Often in these types of buildings we have a hard time finding a suitable mounting construction. Quite often you will see large pieces of plywood hung off of an I-Beam using large pipe clamps or some other method. Then the Access Point is attached to the plywood in some manner. Some of which are better than others. One other issue that arises from these sorts of deployments is how to mount antennas themselves. As we touched on in the first installment, we often are using directional antennas in these sorts of environments. We need to make sure that those are mounted safely, and securely so that they stay pointing in the direction that we need them. This mount solves all of that. 

This is the only mount of any in this post that comes with included hardware. All of the others are BYOH (Bring Your Own Hardware.) Since unboxing is all the rage on the internet, here is what this mount and its included hardware looks like in the box it ships in. 

Here is the bag of hardware itself.

And a few more pictures of everything included in an unnecessary artsy manner. 

It includes four special beam clamps used to attach the mount to a beam. The part that makes these beam clamps special is that they have tapped holes on their bottoms and backs. These holes are tapped so you can use some of the included screws to bolt through the mount and into the beam clamp itself. Below are a few pictures of the beam clamps installed on the mount to give you a better idea of what this looks like. 

In the above pictures you can see the channels that are built into the mount. These channels allow the mount to be installed on I-Beams ranging anywhere from 3"-10". You can also see in the bottom image the screws going through the bottom of the mount and into the beam clamps themselves. Along these same lines, you can see the tapped hole in the back of the beam clamp. Again, providing you even more flexibility in how these can be mounted. While we're on the topic of mounting these, you might also see some other large slots on the mounting surface. These are to place cable or wire secondary clamps wrapped around the beam, in case the beam clamps were to fail. Keeping this and everything that's attached to it from crashing down towards the floor.

One other thing you may have noticed in the pictures of the hardware that Ventev includes with this mount is a long bar with a couple of studs sticking off of it. This is their T-Rail mount. It simply bolts onto the mount itself using some of the included bolts. This provides you the ability to use almost any manufacturers Access Points with this mount. However if using the T-Bar, I would be very careful if mounting this vertically as most T-Bar attachments weren't designed to hold an AP in that direction.

In the last picture you can see the two perpendicular antenna mounts. Often in deployments that would use this sort of mount we're going to utilize external antennas. These provide you a solid mounting platform for those.

One other thing to note with this mount is how large it is. Which makes sense to accommodate as many different mounting scenarios as possible. It also provides you a nice large surface area to place your signage for Access Point name and information. Normally these are being deployed in very tall ceilings, and reading the Access Point name off of a small label applied to the device itself can almost be impossible. This way you can use large, bright, high contrast labeling applied to the mount itself to denote the Access Point name. An interesting side effect of this is it also provides the Access Point a bit of a shroud against dust. Obviously it isn't dust proof, but it's better than nothing.

Here I threw the AP205 used in some of the other pictures onto the T-Bar to provide some scale of the size of the mount. The AP205 is certainly not the largest Access Point out there. But you can see how much more room there is on the mount. One thing these views also do is show off all of the knockouts provided that you can utilize to push cabling through. Both for Access Point connectivity, but also for the antenna cabling to feed through.


Every successful deployment is first going to start with design. However that design is going to be fairly worthless if you cannot properly deploy the Access Points in the required spots called for in the design. Now we have a few more mounts available to make it easier to deploy our coverage exactly where needed.

With that, thanks for reading! If you have absolutely any questions, comments, or concerns, please feel free to reach out!


  1. I'v used the Ventev low profile mount with external antennas. Excellent product! Only thing I had to do was purchase wider beam clamps, as our I-beams were older and thicker than normal. Great post with super info--thanks!
