Overview

The RAM-B-149Z-2-202AU consists of a steel strap base, u-bolt bases, double socket arm and 2.5" dia. round base with 1/4"-20 threaded post. Designed for a clean installation, the included roll bar base accommodates most common tubing sizes on Side By Side’s and ATV's, allowing for the placement of the RAM rubber ball base. Safely concealing a strap clamp in a compact housing, you won't have to worry about exposed sharp edges or unwanted loosening. The camera base contains a 1" rubber ball that is connected to a 2.5" diameter round base. Also, included is a 1/4"-20 threaded steel stud, centered, the round base provides support and stability for cameras that rest on top of it. The male 1/4"-20 threaded steel stud will connect to any standard female thread found on camcorders and digital cameras.

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.
