Step 45: Open the door just enough reach the closer comfortably.

Step 46: With a 3mm Allen wrench, turn both valves clockwise to close them, start with the “120°– 0° valve, then the “7°–0°” valve.

Step 47: Check the marking on the closer arm: An “R” should face up for right hand, left reverse doors, and for left hand, right reverse doors, flip over the arm.

Step 48: Position the arm at roughly a 45° angle. Pull it about 1/8 of a turn toward the latch edge.

The spindle begins on a square and ends on a diamond.

Step 49: Remove and reinstall the closer arm at approximately 90° angle to the door. 

Then rotate the arm toward the door to finalize the preload.

Step 50: Secure the arm with a washer and screw using a 5/32” Allen wrench.

Make sure the screw head is flush with the washer.

Step 51: Slowly turn the “120°–0°” valve counterclockwise with your 3mm Allen wrench.

The arm will extend to close the door.

Step 52: Install the closer track slider.

Step 53: Position the closer track, leaving about 4” of clearance between the closer track slider and the track’s end on the frame side.

Step 54: Use a 12” level to confirm the closer arm and track are level.

Step 55: Fasten two screws at the top ends of the closer track.

Step 56: Open the door to test if the closer arm glides freely.

Step 57: Install the remaining closer track screws.

Step 58: Open the door again to check if the closer arm slides without restriction.

Step 59: Adjust the closer speed. The “7°–0° valve is for latch speed, and “120°–0°” controls swing speed.

Aim for a door that closes in about 6 to 9 seconds from 90°.

Step 60: Open the door again to test your adjustments.

Step 61: Your Single Door installation is now finished!
