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.

Overview

The RAM® Heavy Duty C-Clamp Base with B Size Ball (RAM-B-202U-CC1) is a rugged, steel clamp mount designed for flexible, non-permanent device installation across a wide variety of workspaces. Ideal for desks, tables, carts, or mobile stations, this clamp secures firmly to surfaces ranging from 0" up to 4" in thickness—no minimum edge depth required. Built for durability, the all-steel construction delivers long-lasting performance, while the padded interior safeguards mounting surfaces from scuffs or scratches. Whether in industrial settings or professional offices, this clamp provides a secure hold without compromising aesthetics. This heavy-duty desk clamp includes a B size RAM® ball base for mounting your desired device holder. Additionally, a 4-hole AMPS pattern is located on the side of the clamp, providing a convenient mounting point for smaller mounting solutions like phones, tablets, scanners, and more. With its durable construction and multiple compatibility options, this C-clamp base supports everything from lightweight tablet mounts to heavy-duty docking stations.
