Genuine LiftMaster K77-19130-1 two post bracket kit for the LA400 and LA412 linear actuator swing gate operators.
Fitment: LiftMaster LA400, LA400DC, LA412 and LA412DC. This is the two-post mounting variant — the standard single-post hardware is K77-19130, which is a different kit and is not interchangeable.
Use where the gate post geometry will not allow the standard bracket. Supplied as a complete kit.
