Description
The K19-50038 limit chain (#50, Q140) is a replacement component sold by GatePoint Solutions for LiftMaster gate operators, designed to establish and communicate end-of-travel positions through the operator’s limit mechanism.
In practical terms, technicians install this chain during routine maintenance or when the original chain has worn, stretched, or failed to trigger accurate travel. It supports reliable gate movement, ensures correct open and close endpoints, and helps maintain consistent performance in applications ranging from residential gates to commercial entrances and parking facilities.
Compatible with select LiftMaster commercial gate operators that rely on this limit chain. To confirm compatibility with your model, refer to the operator’s service literature or GatePoint Solutions’ parts reference.
