RAM Yoke Clamp Base - Composite with 1" Rubber Ball

RAP-B-121BU RAM® Composite Yoke Clamp Base with 1" Ball

The RAP-B-121BU is a lightweight, high-strength composite yoke clamp base with a 1" B-size ball. It clamps to glare shields, yokes, rails and tubing without tools, and is a popular cockpit base for GPS units, tablets and radios. On this composite version the ball sits on top of the clamp rather than to the side.

Key Features

• Clamps yokes, rails and other surfaces from 15.9 to 31.8mm (0.625" to 1.25") in diameter
• 1" B-size ball connects to any RAM® B-size double socket arm for near-infinite adjustability
• Modular design: swap the clamp to suit different surfaces, or add a second ball to mount another device
• Light yet strong high-strength composite construction
• Backed by a lifetime warranty

Works With
