The RAM zinc coated u-bolt rail base consists of the 1" diameter ball and socket system with RAM universal 1/4"-20 thread centered on a 2.5" diameter plate.
This mount is designed to be a universal mounting solution for both still and moving cameras. The base has a 1.0" diameter rubber ball designed to sit at right angles to the mounting rail. The metal u-bolts and nuts included will fit a circular rail with a diameter from 1/2" to 1.0". To mount the rail base, place the top of the base on the rail and then slide the u-bolt around the rail, into the holes in the base top. Tighten the screws onto the u-bolt until the base is clamped firmly.
Powder coated marine grade aluminum.
