DUAL-GEAR MECHANISM - The dual-gear mechanism allows you to quickly align your projector with tilt and roll adjustments to achieve your optimal viewing angle. Twist an adjustment knob to align your projector with your screen. Once in position, you can lock your projector in place, ensuring that its alignment won't shift over time | QUICK RELEASE - The quick release mechanism lets you slide the projector assembly into the mounting plate and lock it down. It also aids in speedy removal of the projector for maintenance while keeping the alignment set | PREASSEMBLED DESIGN - The mounting plate and projector mount are already assembled, so all you need to do is attach the plate to the ceiling and secure the mount to the projector | CUSTOM ALIGNMENT - The UPMP-1000 offers up to 360° rotation, ±20° tilt, and ±10° roll adjustments, and the dual-gear mechanism keeps the projector in place without shifting. It is designed to only take a minute to have the projector properly angled towards your screen | MOVABLE ARM FOR UNIVERSAL FITTING - The arms that attach to your projector can be adjusted in nearly any direction, enabling you to attach it to most projectors up to 50 lb and find the center of balance. If your projector has three mounting holes, the arms can be detached to accommodate your setup for added mounting flexibility
