QUESTIONS & ANSWERS

Have a Question?

Ask a Question
  • Do you make a D size track ball?

    Unfortunately no, not at this time. We are always working to improve our designs to offer more mounting options, but the weight of the larger devices normally supported by D size components makes those parts problematic for use with our track system.

  • Is that possible to have 3D files of your products?

    I'm sorry but we are not able to share 3D models of any of our parts. We do have technical 2D drawings available for some components though. Any technical drawings that are available will be provided on the applicable product page.

  • What’s the diameter of the rubber friction washer?

    The outer diameter of the rubber friction washer is 1.5".

*Approximate capacity for a standard ball with a mid-length arm. Shorter arms and steel-reinforced posts increase real-world capacity.

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.
