1. The installation of CM20 requires a certain level of professional expertise. We strongly recommend entrusting this
task to professional construction workers whenever possible.
2.If you choose to install it yourself, please make sure to have someone assist you for safety reasons.
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
