This feature is present across all new Exxentric devices. It’s intended to act as a buffer between the kBox or kPulley device and its Pulley Block, hence it’s a consumable part that may need replacing from time to time.

Upon disconnecting the Drive Belt from your device (with a 3 mm hex key), you may refer to the instructions below to guide you through how to mount a new rubber layer.



These rubber casings are designed to protect Pulley Blocks from unexpected impact caused by collisions with the device that it’s mounted to, which prolongs both the device’s as well as the Pulley Block’s lifespan and in turn makes it more robust.
