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® Double Socket Arm (RAM-B-201U) is a rugged medium-length double socket arm compatible with B size rubber ball adapters and bases. A single spring inside the arm pushes one end open as the arm is loosened, allowing for easy rotation of the ball and socket connection at both ends. This ball-and-socket technology allows for near-infinite adjustment and perfect viewing angles when used with RAM® rubber ball bases.

QUESTIONS & ANSWERS

Have a Question?

Ask a Question
  • Is this part number able to accommodate both the B and C size balls?

    No, this part is designed specifically for the B size 1" ball bases.

    However, the RAP-BC-201U has a B size socket on one end, and a C size socket on the other end.

  • What are the torque specifications for the medium arm?

    We do not publish torque specifications for our socket arms. They are designed to be hand-tightened only; the use of tools is not recommended
