About Brookline Door Closers

GENERAL INFORMATION:

Door Closers are mechanical devices that use tension springs and hydraulics to control the closing and latching speed of a door. Door Closers are primarily used on Fire Doors to restrict the movement of smoke and heat into the path of egress. Door Closers are also used on exterior doors to help maintain temperature inside a structure and provide constant latching to help maintain physical security. Door Closers come in a variety of types, but regardless of the different types, they all perform the same basic functions.
