Mounting Questions

Where to mount the projector is one of the first questions new or prospective projector-buyers have to ask themselves.

This method is frequently favored for the uncluttered and professional look it adds to any home theater or office. Much like mounting anything else, what you need depends on what you have to work with. There are just as many variations in ceilings are there are on walls and before you start any installation process you want to make sure you have everything you need to complete it. The Crimson AV CA8HD Heavy Duty 8x8 Inch Ceiling Adapter for Long Drops is one piece of the ceiling mount puzzle you may need to complete your installation.
