Closing devices

- Mar 07, 2019-

A properly sized closing device is the last of the “basic” fire door hardware requirements. A 7 SDI 118-2001 fire door must be in a closed and latched position to serve as a protective barrier in the event of a fire. For this reason, either spring hinges or a listed door closer is required. When the door is closed, the closer has served its role as a protective device.
