RAM-B-201U RAM® Double Socket Arm – B Size Medium (Aluminium)

The RAM-B-201U is the heart of the RAM mounting system: a marine-grade aluminium double socket arm that suits 1" B Series ball fittings at both ends. Simply choose a base style and a device adapter. Looking for the composite version instead? See RAP-B-201U.

Key Features

• Standard overall length of 94mm, 76mm socket-to-socket
• Attaches to any B Size RAM® ball component, including mounting bases and device holders
• Double ball-and-socket technology allows near-infinite adjustability
• Powder-coated, marine-grade aluminium construction

A single spring inside the arm opens the end sockets, allowing you to pivot the ball-and-socket connection for almost infinite adjustment and perfect viewing angles.
