Description
Overview
The RAM-B-252U is a compact bolt head adapter ball base with an 11mm hole and a RAM B Size 1" rubber ball. It is designed to create a RAM mounting point using compatible motorcycle mirror frames, handlebar pinch bolts, and similar bolt locations.
This base is commonly used on motorcycles, especially BMW models, where a low-profile mounting point is needed without using a handlebar clamp or suction cup. Once installed, it connects to RAM B Size double socket arms, holders, cradles, and adapters.
