This product, the Universal Projector Wall Mount, is a highly practical and versatile device designed for multiple projection and imaging needs. It offers wide compatibility, suitable for single - hole universal projectors or mini projectors with standard 1/4 in. (6 mm/0.23 in.) screws. Additionally, it can hold digital cameras, camcorders, SLRs, and anti - theft surveillance cameras. However, it's not compatible with screws of 0.15 in. and 0.25 in. Constructed from premium cold - rolled steel with a double rotating shaft structure, it ensures stability and durability, capable of supporting projectors up to 3 kg/6.6 lbs. Adjustability is a key feature. The stand allows for a tilt of +/- 180°, a swivel of +/- 180°, and 360° rotation of the angle adjustment bracket. It's extendable and foldable, saving both projection space and physical space. The black powder - coated finish makes it aesthetically pleasing and suitable for most home and office environments. Installation is straightforward, with all necessary hardware and instructions provided. But it's not suitable for vaulted ceilings or regular drywall. The package contains a main bracket mount, a mounting hardware kit, five cable ties, and a user manual. Remember to fasten the knob under the ball head first and then tighten the side knob to fix the projection angle.
