Extron UPB 125 (part number 70-902-03) — universal projector mounting bracket in white, rated for projectors up to 40 lbs (18.1 kg).

Every projector manufacturer sells its own mount, which means an integrator either stocks a dozen of them or waits on a special order. The UPB 125 removes that problem: one bracket, the projector hardware in the box, and a two-piece design that separates the ceiling-side arm from the projector-side plate. Alignment is handled on three independent axes — up to 5 degrees of roll, 20 degrees of pitch and a full 360 degrees of yaw — so the image can be squared to the screen without fighting one adjustment against another. Once the geometry is right it can be locked, and it survives the projector being taken down for a lamp or filter change: refit the arm assembly and the alignment comes back with it. The bracket accepts a 1.5-inch outside-diameter, 11.5 NPT/NPS pipe.
