The LiftMaster 11-35043 LIMIT SHAFT, BGH is a genuine OEM replacement component engineered for the LiftMaster BGH commercial door operator. This shaft is a core element of the limit switch assembly, transmitting rotation to the limit cams so the operator can accurately detect and stop at the programmed open and close positions. Replacing a worn or damaged limit shaft helps restore precise travel control on commercial and industrial doors where the BGH operator is installed, including applications such as sectional doors, rolling doors, and grilles.
Designed to match LiftMaster factory specifications, the 11-35043 fits the BGH model identified in LiftMaster parts diagrams. Installation typically involves accessing the operator’s limit housing, removing the existing shaft and associated retainers, transferring or re-seating the limit cams as required, and then re-establishing the door’s open/close limits using the operator’s standard adjustment procedure. For safety, disconnect power and follow lockout/tagout practices; ensure the door is secured and supported before service. LiftMaster recommends service by qualified personnel. This OEM limit shaft is an ideal replacement part for maintenance and repair of the LiftMaster BGH commercial door operator’s limit switch mechanism.
