  • Using the template at the top of page 2, see figure 2, select the angle of opening desired. Locate and mark for 4 holes on the door for the closer body and 2 holes on the frame for the arm shoe.
  • 2. Prepare the door and frame for fasteners using the information from the "Preparation for Fasteners" chart, figure 3 on page 2.
  • 3. Install closer body to door as shown.

  • 4. Disassemble holder loop assembly from the main arm assembly by loosening set screw.
  • 5. Fasten holder loop assembly to frame face as shown.

NOTE: Holder Adjustment Nut must be UP for Right Hand Door DOWN for Left Hand Door

6. Following the main arm indexing illustrations in figure 4, place main arm onto the closer pinion shaft. Install and tighten main arm screw with a 1/2" wrench.

7. Open door slightly and assemble connecting rod into holder loop. Close and latch door. Adjust secondary arm assembly so that the main arm is perpendicular to face of door. Tighten set screw securely.

Hold Open Adjustment Open door to angle of hold open desired and tighten holder adjustment nut with wrench supplied.

9. Closing Tension - Place wrench (packed with door closer) on ratchet as shown. Swing wrench away from hinge to wind spring between 3 to 10 notches, engage arm dog in ratchet, increase or decrease spring power to suit conditions.

Caution - Underwound spring (less than 3 notches) or overwound spring (more than 10 notches) will cause spring breakage.

Right Hand Door

Regular Arm Closer Adjustment -

Closing Speed ... Controlled by the regulating valve on the end of the closer closest to the hinge.

Sweep Speed ... Controls the door's speed in the sweep speed range, see illustration. Full 360° clockwise turns decrease the sweep speed. Full 360° counter-clockwise turns increase the sweep speed.

Latch Speed ... Controls the door's speed in the latch speed range, see illustration. A partial turn, up to a maximum of 1/2 turn (180°) in either direction determines the latch speed.

Backcheck ... Controlled by the regulating valve on the end of the closer farthest from the hinge. Backcheck cushions or slows the door opening speed near the end of the opening cycle. Full 360° clockwise turns increases resistance to opening. Full 360° counter-clockwise turns decreases resistance to opening. Note: If backcheck is encountered extremely early in the opening cycle, rotate the valve 1/2 turn (180°) to eliminate early opening resistance.

Caution ... To avoid damage to closer,

never fully close the backcheck regulating

Backcheck Control Figure 7. Full turns for Backcheck Range

Parallel Arm Closer Adjustment -

Closing Speed ... Controlled by the regulating valve on the end of the closer farthest from the hinge.

Sweep Speed ... Controls the door's speed in the sweep speed range, see illustration. Full 360° clockwise turns decrease the sweep speed. Full 360° counter-clockwise turns increase the sweep speed.

Latch Speed ... Controls the door's speed in the latch speed range, see illustration. A partial turn, up to a maximum of 1/2 turn (180°) in either direction determines the latch speed.

Backcheck ... Controlled by the regulating valve on the end of the closer closest to the hinge. Backcheck cushions or slows the door opening speed near the end of the opening cycle. Full 360° clockwise turns increases resistance to opening. Full 360° counter-clockwise turns decreases resistance to opening. Note: If backcheck is encountered extremely early in the opening cycle, rotate the valve 1/2 turn (180°) to eliminate early opening resistance.

Caution ... To avoid damage to closer, never fully close the backcheck regulating valve.

To Reverse Closer Hand

Installation Sequence

  • Using the template at the top of page 5, see figure 9, select the angle of opening desired. Locate and mark for 4 holes on the door for either the closer body or #88 drop plate and 4 holes on the frame for the soffit plate.
  • 2. Prepare the door and frame for fasteners using the information from the "Preparation for Fasteners" chart, figure 10 on page 5.
  • 3. Install closer body to door as shown. If a backplate is used, mount it first, then fasten the closer to the backplate.

  • 4. Disassemble holder loop assembly from the main arm assembly by loosening set screw.
  • 5. Fasten soffit plate to frame soffit with 4 mounting screws.

6. Following the main arm indexing illustrations in figure 11, place main arm onto the closer pinion shaft. Install and tighten main arm screw with a 1/2" wrench.

7. Open door slightly and assemble connecting rod into holder loop. Close and latch door. Adjust secondary arm assembly so that the main arm is approximately 2° from parallel with face of door. Tighten set screw securely.

8. Hold Open Adjustment Open door to angle of hold open desired and tighten holder adjustment nut with wrench supplied.

9. Closing Tension - Place wrench (packed with door closer) on ratchet as shown. Swing wrench toward hinge to wind spring between 3 to 10 notches, engage arm dog in ratchet, increase or decrease spring power to suit conditions.
