This belt replaces a 3/16" or 0.21" round endless O-ring belt. It is made from 0.139" cord. NOTE: The twisted belt should be 6% shorter than the round O-ring belt it replaces! Twisted belts are typically stretched 16-20%. Example: a 13.50" endless oring belt would commonly be replaced by a Twisted 12.75".

Measure the twisted belt tip-to-tip, do not include the hook in the cut-length. Note gently crimping the standard metal hooks after installation may increase belt lifespan.

This twisted belt can be used to provide extra drive vs a twisted 3/16" without being too much thicker.
