The RunRight® rubber suspension unit RSR has 4 bore holes in the inner square and is designed to transmit alternating motions from the neutral position.
A bolt through either two, or all four of the bore holes, can be used to mount a lever to either side of the unit.
They are manufactured with aluminum housings and inner squares.
They have standard Tensys® 10 rubber inserts and can be used for applications operating within a -40° to 180°F (-40° to 80°C) temperature range.
