RAM® Part Numbers: A how to guide
RAM Ball Sizes
A size ball 0.56" diameter ball
B size ball 1" diameter ball
C size ball 1.5" diameter ball
D size ball 2.25" diameter ball
E size ball 3.38" diameter ball
To help you understand the part number format used, we are providing the following example. It is two different sizes of a basic RAM mounting system including the corresponding arm, round base with ball.
RAM-201U this is a double socket arm in a 1.5" C-size ball.
RAM-B-201U This is a double socket arm in a 1" B-size ball.
Note: The C size 1 .5" ball does not have a letter C following the RAM- prefix code, while all other sizes do require a letter.
Important: Be careful to make sure you have the letter in the proper location of the part number so you order the correct size system or component. If in any doubt, please contact us.
Weight Capacities (at 1g load)
B size 1" ball mount for units up to 0.907kg
C size 1.5" ball mount for units up to 1.81kg
D size 2.25" ball mount for units up to 2.72kg
E size 3.38" ball mount for units up to 6.8kg
RAM Prefix Code
RAM fitting with the prefix RAM are made of marine grade aluminium with a black powder coated finish, stainless steel hardware and rubber balls, providing lightweight, strength and corrosion resistance.
Some of these parts are also available in composite construction. In this case the mount part number has the prefix code RAP.Other RAM codes

RAM Device Cradles and Holders
The RAM range includes a large number of device specific cradles and holders suitable for many devices. We have a selection of complete mounting solutions available however all can be built from component parts. Most device cradles use a RAM-X-202U round base on the back to allow then to mate with the rest of the RAM system. The exceptions to this are the X-grips with the code suffix BU which have their own ball already and the smaller device cradles which accept a RAM-X-238U diamond shaped mounting plate.
Hopefully this has helped to clarify the system a little and allow you to navigate around the RAM part numbering system. If you get stuck we're here to help.
