Description
Overview
The RAM-B-121BAU is a yoke clamp rail base with a RAM B Size 1" ball and a 1/4"-20 threaded hole. It is designed to clamp onto round rails from 0.625" to 1.25" in diameter, creating a secure RAM mounting point without drilling.
The ball is positioned at a right angle to the clamp, allowing it to sit parallel to the rail when installed. This base is commonly used in aviation, vehicle, marine, industrial, and equipment applications where a compact clamp-style RAM B Size mounting point is needed.
