The need for an auxiliary bracket during the installation of the CM20 depends mainly on the frame
and the load-bearing capacity of the suspended ceiling tiles.
- Common suspended ceiling tiles materials include gypsum, metal, and PVC.
- If your suspended ceiling tiles has a load-bearing capacity lower than 1.38KG, it is recommended
to use a bracing bridge.
- The suspension bracket requires the load-bearing capacity of your ceiling frame to be no less
than 2.8KG.
- The adjustable range of the bracing bridge is 400-438mm/600-638mm/2'.
- The slot width compatibility of the ceiling tiles (T-bar) includes: 22mm, 24mm, 32mm, and 38mm.
- The slot width compatibility of the ceiling tiles (triangle) includes: 25mm, 30mm, 35mm.
- The adjustable range of the length-adjustable pole is 33cm-60cm.
1. The installation of CM20 requires a certain level of professional expertise. We strongly
recommend entrusting this task to professional construction workers whenever possible.
