Prudhomme LR180 Lock (LR180EG190A / LR180ED190A) – 24V Elevator Interlock

Prudhomme LR180-series electrical interlock supplied complete with adjustable bolt-length option, door-contact/bridge, and lock-keeper.

This configuration is similar to the widely used LR180EG390A/24 and LR180ED390A/24 locks but is supplied as the LR180EG190A/24/CACF/SH21 (left-hand) and LR180ED190A/24/CACF/SH21 (right-hand) versions, including the door-contact/bridge and lock-keeper.

Common model designation variations include LR180EG190A/24/CACF/SH21, LR180ED190A/24/CACF/SH21, LR180EG190A24CACFSH21, LR180ED190A24CACFSH21, LR180ED/190A24CACFSH21, and similar shorthand forms. When matching a replacement, the most reliable identifiers are the full Prudhomme reference and the physical handing (left or right).

These 24V LR180 interlocks provide mechanical door locking with electrical monitoring for elevator or vertical platform lift landing-door applications. The adjustable bolt (pin) length and the included contact bridge + lock-keeper make this a more complete assembly for installations that require those components.
