Regular Arm: This is the only pull-side application where a double lever arm is used. It is the most power efficient application for a door closer. Since the arm assembly projects directly out from the door frame, the Regular Arm mounting may present aesthetic issues. Top Jamb: For efficiency reasons this application provides the best alternative to the Regular Arm mounting. Top Jamb mounting provides the best door control for doors in exterior walls that swing out of the building. The entire door closer and arm assemble project from the frame, similar to the Regular Arm mounting. Parallel Arm: This application provides the most appealing appearance for a over head surface mounted door closer having a double lever arm. It is also beneficial in abuse (vandalism) prone areas. It is on the push side of the door and the arm assembly extends almost parallel to the door. When the door is closed there is very little hardware projecting from the frame face. Parallel Arm application will also allow the door to swing 180 degrees. Due to the geometry of the arm, it is approximately 25% less power efficient than Regular Arm or Top Jamb mounting. Hold Open Arm: is the ability of the door closer to hold the door in the open position. Most over head door closers achieve this function via a special type arm (Hold Open Arm).
