The RAM® Quick-Draw™ Jr. Printer Mount with Medium RAM® Tough-Claw™ (RAM-404-VPR-104U) is a spring-loaded, rugged mounting solution that securely attaches to rails and bars. At each end of the spring loaded cradle, there are small side clamp plates that fit cleanly around the edges of the device. Paired with the Tough-Claw™ base, this mount installs quickly and tool-free on round, square, and irregular rails from 1" to 1.6" in diameter. The RAM® double socket arm and ball-and-socket system deliver near-infinite adjustability, making it easy to position your printer exactly where you need it. Be sure to verify your printer’s dimensions, including any case or sleeve, to ensure proper fit.
