Description
The RAM-B-408-37-62U is a small RAM® Torque™ rail base with a RAM® B Size 1" rubber ball. It is designed to clamp onto small round rails from 0.375" to 0.625" in diameter, creating a secure RAM® ball mounting point without drilling.
This compact rail base is commonly used on scooter mirror rails, vehicle headrest posts, small equipment rails, and other narrow tubular mounting locations. Included bushings and a rubber strip help provide a snug fit while protecting the mounting surface, and nylock nuts help prevent loosening in high-vibration environments.
