Door Closers and Exit Hardware
Door closers are common in public buildings for sound control and fire control. Door closers operate pneumatically or hydraulically and have an adjustable spring mechanism for variations in speed and strength of closing action. Hydraulic closers are either surface mounted or concealed in the head frame or jamb.

Exit hardware (panic hardware) allows for easy exiting of a building and is commonly used in buildings with high occupancy such as schools and auditoriums. Exit devices can be installed on single doors, double egress and double doors. A door coordinator is installed on double doors to ensure that both doors close in proper sequence when opened at the same time. Dogging devices control access from the outside.
