The RAM High Strength Plastic Rail Mount consists of the 1" dia. ball and socket system with RAM Plastic 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.
BASE DESIGN:
The High Strength Plastic Rail Base has a 1.0 inch diameter Rubber Ball designed to sit at right angles to the mounting rail. The Rail 'U' Clamp will fit a circular rail with diameter up to 1.0 inch.
For a larger rail, you can purchase the RAM-B-231Z Aluminum Rail Base with Zinc Coated U-Bolt for circular rails with diameter from 1/2 to 1 3/8 inches.
NOTE: Placing a rubber lining (not included) between the tube and the mount for a tube with a diameter less than 1.0 inch will help the base 'grab' the rail.
IMPORTANT NOTE FOR MOTORCYCLES USES:
This base is NOT recommended for Motorcycles due to the heavy vibration. An alternative would be the RAM-B-231 Stainless Steel U-Bolt Base and the RAM-B-149 Stainless Steel U-Bolt System.
ARM DESIGN:
The High Strength Plastic Standard Length Double Socket Arm is 3.0" long when measured between socket centers.
CRADLE DESIGN:
 The High Strength Plastic Universal Camera Plate has a 1.0" diameter Rubber Ball connected at right angles to a 2.5" diameter Plate with a centered 1/4"-20 thread. The plate adds support to the thread, by allowing the camera to rest on the plate, creating a stable connection with the camera.
Note: The male 1/4" long, 1/4"-20 thread in the middle of the 2.5" diameter plate will connect to the standard female thread found at the bottom of most still and video cameras. An alternative to this camera mounting system is the Aluminum 2.5" Plate with 1/4"-20 Thread (RAM-B-202A) or the Male 1/4"-20 Threaded Ball (RAM-B-237).
