This belt replaces a 3/16" round endless O-ring belt. It is made from 1/8" (3.2mm) 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 3/16 x 13.50" endless oring belt would commonly be replaced by a Twisted 3/16 x 12.75".

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