Honeywell Left-Hand Door Interlock for Harmar Summit Lifts

This Honeywell interlock is used on select Harmar and Summit accessibility lifts, wheelchair lifts, and dumbwaiters. It replaces legacy Honeywell #CDILBS1W and Harmar Summit #46221. Handing is determined while standing outside the car and looking in; this left-hand lock installs on the left side of the door or gate when facing the car from the outside.

This listing includes the replacement lock only. The existing wire harness is not included and should be retained from the original installation and transferred to the replacement lock. Once remaining Honeywell inventory is exhausted, this interlock will be superseded by the compatible Suns alternative found here.
