Overview

The RAM Torque™ Rail Base accommodates rails and bars ranging from 1.5” to 2” in diameter – the perfect mounting solution for your ATV or Side By Side. The include B size hex ball adapter can connect to either side of the Torque base, and is suitable for rugged environments for supporting action cameras, spotlights or other devices. Two sizing inserts – one for attachment to 1.5” rails and the other for attachment to 1.75” rails – are included to create a tight hold while nylon-insert lock nuts prevent loosening in high-vibration environments. Available separately, the RAM B Size Ball Add-On allows you to attach an additional B Size Ball to the Torque™ Rail Base for mounting multiple devices.

Reading part numbers

The letter after RAM tells you the ball size: RAM-B-166 uses a 1" B ball, while RAM-D-201 uses a 2.25" D ball. C size parts are the exception and carry no letter, so RAM-201U is a C size arm.
