Additional Adapters for Channel and Beam Ceiling Rails
The most common type of suspended ceiling support rail (the support for the ceiling tiles) is the ceiling
Tile rail or T-rail for short. You can attach a ceiling grid clip directly to a T-rail ceiling rail. However,
other types of ceiling rails, such as channel rails and beam rails, require an additional adapter clip
(AIR-CHNL-ADAPTER). You need two adapter clips for each router. Set screws on the clips hold them
securely on the ceiling rail.
