This is a very well-built telescoping mount for mini-projectors or any equipment which has the standard threaded base (like camera equipment, etc). Solid aluminum threaded base, 2-piece telescoping beam, 360 degree swivel camera mount. Hollow beam to hide wiring. They say this is designed for a 4.4 pound maxinum load, which is adequate for mini-projectors and most camera equipment. Can ceiling mount or wall mount and it extends from about 12 inches to about 18 inches. We will use it as a ceiling mount for a mini-projector.
