Cookson Retrofit Chain Hoist 804-299-4472

This is an installation of a Cookson Retrofit Chain Hoist with Simple Test device on an old Raynor Rolling Fire Door. The governor on the old door was not sufficiently slowing the door down enough to allow the door to drop within the required drop speed. We replaced the governor and chain hoist with this new device.

  1. I love when u get an old POS to drop right 20 times in a row.. Then u get the Marshall there and the damn thing won’t drop.

  2. Those things are nice getting rid of the old tension release crap. I’ve done some retrofit operators that are really sweet. Made by us gear. Sometimes they rebrand them as lawrence and cookson ops.
