RAM® RAM-B-231Z-2U Rail & Bar Base – B Size

The RAM-B-231Z-2U is designed for a clean, secure, and versatile installation on UTVs and ATVs. Engineered to suit most common rail and bar sizes, this compact base features a concealed strap clamp that eliminates exposed sharp edges while helping prevent loosening in rough conditions.

The kit includes both a strap clamp and a zinc-coated metal U-bolt, allowing you to choose the best mounting method for your setup or relocate the mount to another position if needed. Protective black caps neatly cover the exposed ends of the U-bolt for a tidy, finished appearance.

Equipped with a 25 mm (B size) RAM® rubber ball, the base connects seamlessly to any B size RAM® double socket arm. The proven ball-and-socket design provides near-infinite adjustability, making it easy to position your device exactly where you want it.

Manufactured from powder-coated, marine-grade aluminium and high-strength composite materials, the RAM-B-231Z-2U is built to handle demanding off-road and outdoor environments. As with all genuine RAM® components, it is backed by a lifetime warranty.

Availability:

The RAM Mounts warehouse in Australia is well stocked with the most popular products, but for the less popular products they may need to be ordered in from the USA. That's fine, but RAM Mounts have an approximate 2 month manufacturing lead time.

If our site shows this item as in stock (see above), great! It will ship immediately from our warehouse. If it shows as Pre-Order, this means it will need to be ordered in from the USA, which may take some time unfortunately.
