Description
The RAM-B-346U is an offset reservoir cover ball base designed to mount over an existing motorcycle brake or clutch reservoir cover. It provides a B Size 1" RAM rubber ball for connecting a compatible RAM double socket arm, device holder, or other B Size mounting component.
This base is useful when you need a clean, low-profile mounting point on a motorcycle handlebar area without using a clamp or drill-down base. It installs using the reservoir cover screw holes and the included replacement hardware.
