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.

Availability:

RAM Mounts supply is pretty good in Australia, but they have thousands of parts so we can't stock them all on our shelves. If our site shows this item as in stock in our warehouse (see above), great! It will ship immediately from our warehouse. If it shows as Pre-Order, we get fortnightly shipments from RAM Mounts and our site should show if it's in stock in Australia.

• If in stock in Australia we can have it in about a week or less
• If it's not in stock in Australia, unfortunately the ETA can be quite long, as RAM Mounts in the USA have a manufacturing lead time of 6-8 weeks. But if you'd like to contact us we can find out a more accurate ETA for you
