Fitment: all LiftMaster Maxum operators.
Extends the operating range down to −40°F. Needs no operator cover, but does need its own 120VAC feed.
Ordering the right part depends on the full model number, which is printed on the operator label. Call GateHouse Supplies if you are not sure — we service these units every day.
