Overview

The RAM-B-108BU consists of a B size 1" rubber ball connected at a right angle to a V-shaped base, and accommodates rails from 1" to 2.1" in diameter. To mount the RAM-B-108BU base, place the saddle-shaped plate on the rail and then wrap the metal clamp strap around the rail and plate. Tighten the knob on the metal strap with a screwdriver until it has a firm hold on the rail. The RAM-B-108BU is an alternative mounting base for Beechcraft airplanes with a “throw over yoke."

QUESTIONS & ANSWERS

Have a Question?

Ask a Question
  • Will this fit my yoke?

    This is commonly used with the Beechcraft throw-over yokes, but as long as the yoke on your aircraft is between 1" and 2.1" this will be compatible

  • Can I fit a C size ball to this. (I bought this B size but my mount is slipping so I think I need to go up a ball size)

    No, the B size ball included as part of a RAM-B-108BU is injection molded onto the post of that mount and cannot be changed.  The RAM-108BU is a comparable mount that has the 1.5" diameter C size ball.

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.
