GENERAL NOTES
1. Consult installation instructions supplied with door closer
2. Hollow metal doors and hollow metal frames require reinforcement in the areas of the door closer and arm
plate mounting
3. Through bolts with sex nuts must be used in wooden Fire Door applications and on hollow metal doors with
no local reinforcement
4. Threaded holes in door or frame require a minimum 12 GA (0.110”) thickness
5. Indicated dimensions are based on industry standard door and frames with 1/8” (3 mm) clearance and 5/8”
(16 mm) stop height and properly leveled doors and frames.
6. Select the door closer and arm plate positions based on the door opening angle
7. If a drop plate is used, ensure door closer mounting screws do not protrude beyond the back surface of the
drop plate. Screws must engage a minimum of 3 threads inside the drop plate
8. For a door closer to operate properly, the arm must be positioned and operate horizontally and the door must
be supported on ball bearing hinges of sufficient size for the door used.
9. Perform a operational test on the door and adjust door closer as indication in the installation instructions
supplied with the door closer
For through bolt installations,
drill 9/32” hole through door on
the closer side and 3/8” hole on
the other side through door skin
for hollow metal doors. For wood

screws) and door closer to drop plate using 4 machine screws.
5. Attach arm plate to soffit using 4 screws. Install a fifth screw with spacer block if or additional
support, if soffit width is narrow
6 Using a wrench on the door closer bottom shaft, turn the shaft towards the hinge about 30°
(for pre-loading), and place main arm on the closer top shaft. Insert the main arm screw into
the top shaft and tighten.
