Our universal projector ceiling installation solves compatibility issues - designed for 4-hole VESA standard projectors (75x75/100x100) and single hole models, this is the only installation you need in your home, office, or classroom settings. This bracket is made of aluminum alloy and features an adjustable length rod (with a telescopic design that allows you to customize the height to fit the distance from the ceiling to the screen) and a detachable 4-wire base: connect to a standard projector's 4-hole board or replace with a smaller/non VESA device's single hole adapter (using 6mm screws). It takes a few minutes to install using the accompanying hardware, and the sturdy structure can support up to 22 pounds (10 kilograms) of weight, which is stable enough for most home theaters and office projectors.
