RAM® RAM-103U Mounting Kit – C Size Ball & Socket System

The RAM-103U is a versatile and reliable mounting solution built around RAM®’s proven 38 mm (C size) ball-and-socket system. Designed for compatibility with a wide range of RAM® mounting bases and device cradles, it provides a strong and flexible foundation for achieving the ideal viewing position.

This mount features a 38 mm rubber ball set at right angles to a 63.5 mm round base. The base is pre-drilled with the universal AMPS hole pattern, making it easy to connect to a broad range of RAM® device holders and accessories.

The included medium-length double socket arm allows adjustment at both ends, delivering near-infinite positioning flexibility while helping to dampen vibration for a more stable and secure setup.

Manufactured from powder-coated, marine-grade aluminium, the RAM-103U is built for durability and long-term reliability in demanding environments. Like all genuine RAM® products, it is backed by a lifetime warranty for added peace of mind.
