DCCA 41 Cush Stop Arm
Door Closer Arm (non-hold open)
CUSH is a shortened term for Cush-N-Stop, and it’s used in conjunction with LCN closers. You may also see it abbreviated as “CNS” (Other closer manufacturers offer the same feature but use different terminology to describe it). The CUSH arm has a door stop built into it, so when the arm reaches a certain point in the opening cycle of the door, the arm hits the stop on the shoe and stops the door.
