RAM® Mounts: Ball Sizes & Weight Capacities

This video explains RAM® ball sizes and weight capacity guidance, helping customers choose between A, B, C, D and E size components for different devices and mounting conditions.

What this video covers

This video explains how RAM® ball sizes relate to device weight, mounting environment and expected vibration. It is a useful guide for choosing between A, B, C, D and E size RAM® mounting components.

The video covers the typical ball diameter for each size and explains that smaller sizes are suited to lighter devices, while larger sizes are used for heavier electronics or more demanding environments. It also highlights that rougher applications, such as boats, forklifts and other high-vibration setups, may call for moving up a size.

This page is especially helpful if you are building a mount from separate parts and need to make sure the holder, arm and base are from the same RAM® size family.
