The RAM-B-149ZU consists of a zinc-coated U-bolt base, double socket arm, and diamond adapter base. The diamond adapter base has a hole pattern that matches the industry standard AMPS hole pattern and will connect to a large variety of RAM components. Included is hardware that will accommodate rails from .5″ to 1.25″ in diameter. A composite rail adapter can narrow the rail to a minimum width of 0.5″. Also included is a B size medium length double socket arm featuring adjustment points at both ends, allowing for near-infinite adjustability.
