This heavy gauge aluminum alloy tray was designed to be light-weight yet rugged enough to support the heaviest 17” laptop. Unlike any other support of it’s kind it comes with a Mouse Tray that quickly fastens on and will support the heaviest handed mouser users. The i-Visor OS Support Platform attaches to any tripod with a 3/8” stud. It was specific designed to accommodate the integral strapping system on both the i-Visor LS and i-Visor ON-Set.
