100% Brand new authentic Linear Part
Replacement trolley for LSO50, LDO33 LDCO800 LCO75 and LDO50 garage door operators
Linear Trolley Carriage for Chain or Belt Drive Models

If you old trolley has left excess black dust on your opener rail, has a lot of play from wear, or has cracked, this will get your Linear operator back in business.
