Correct the MR's come with a mounting kit. Part of that kit includes little twist clamps (bottom right of picture below) that mount and slide on the grid then the bracket mounts to those clamps.
Both of you are correct if I were mounting to a T-Rail drop ceiling grid.
In my case, I need to mount these AP's to a Channel drop ceiling grid as shown in the center image. The left image is the T-Rail grid and the right one is a Beam grid. For the middle and right Cisco sells the AIR-CHNL-ADAPTER adapter to mount all of their AP's to both of these types of ceiling grids. I cannot use that adapter to mount Meraki AP's so I was wondering if anyone knows of a viable solution for these two other types of celings.
I saw this post and thought I would offer assistance. In the past you had to use Cisco's AIR-CHNL-ADAPTER brackets and mount the Meraki Adapters to it. Meraki has its own clips that work like the AIR-CHNL-ADAPTER brackets, but look like the normal adapters that are shipped with APs. The difference is the clips are deeper. I know it's hard to describe but this part number: MA-MNT-CLG-1 includes a pair of deep drop ceiling clips for channel rail as well as spare T-Rail adapter clips which supports both recessed T-Rail and flush T-Rail. The deep drop ceiling clip works well with "Armstrong Silhouette" and similar ceiling grids which are found in newer building designs, its basically a channel rail (not a T-Rail). This kit is compatible with all Meraki MR access points and MV21 & MV71 security cameras.
Everyone knows the T-Rail here's a good picture of it:
Meraki APs Come with an adapter for this by default. but If you want to mount on
the channel rails pictured above, you will want to order MA-MNT-CLG-1
separately when ordering your APs.
Good luck out there all!!!
HTH!
