AP285 (plastic canister) rope tensioner replacement. Fits, but only after some modifications. The coil spring is rubbing against the back of the canister and the plug is too large to fit through the hole in the canister. Also, one of the electrical connectors is too long to fit the original connector. I had to repeat all three elements. When installed, the ability to roll up the cable was questionable at best. I removed it and fixed the OEM retractor. Consider this a small financial loss as there is no refund from Revain.
