The RAM Mounts RAM-235U is a double U-bolt ball base for attaching a RAM mounting system to a compatible rail. Its C-size, 1.5-inch ball forms the connection point for a C-size RAM double socket arm, which can be paired with a separate holder or device mount.
The clamp fits rails measuring 1 to 1.25 inches in diameter. The base is made from powder-coated, marine-grade aluminum and is supplied with two U-bolts, four Nyloc nuts and four rubber caps. These parts provide the hardware for fitting the base to a rail; the socket arm and device holder are separate components.
