218189-01 Linear Garage Door Opener Trolley Assembly
The garage door opener trolley travels back and forth on the operator belt or chain rail. The trolley has a red rope (not included) that will disengage the opener from the door so the garage door can be lifted manually. To reconnect the trolley the release lever is flipped up and the door is raised or lowered until the opener reconnects.
Depending on how often the garage door opener is used the opener trolley assembly can wear out. The 218189-01 Linear trolley assembly can replace the damaged or worn out trolley on the HCT (chain) and HBT (belt) opener rails.
