Installation Instructions
- Select the angle of the opening and use the dimensions shown on and Dimension Chart below to locate 4 holes on the top side of the door for the closer body or 213 drop plate, only if required, and 5 holes on stop and/or rabbet for Soffit Plate. For applications not covered in these instructions, a separate template will be required.
- Prepare door and frame for fasteners. See “Preparation for Fasteners”,
- Set closer power for door size using the Power Adjustment Chart below. Use the 1/8″ hex wrench supplied to adjust the Power Adjustment Shaft … 15 turns maximum. Turn nut CLOCKWISE to Increase, COUNTER-CLOCKWISE to Decrease power. See Page 6 for the illustration of this step.
- Mount 213 Dropplate … only if required.
- Install closer with a power adjustment screw toward the hinge edge of the door. Note: If using cover, thread in screws before mounting closer. Leave enough gap between the head of the screw and the closer to slide the cover on.
- With the door closed, use a wrench to rotate the pinion shaft as illustrated below, see Arm Mounting Details. Caution: Closer arm is under spring tension and may be difficult to rotate.
- Install Main Arm: Close valves – ‘S’ and ‘L’, then turn the pinion shaft more than 50° to permit proper alignment of arms mark with pinion flat –
- ‘L’ for Left-hand door.
- ‘R’ for Right-hand door.
- See “Main Arm Installation Instructions” below.
- Make closer adjustments before installing the cover … CAUTION: Do not back valves out of closer completely or a leak will result.
- Reopen valves by turning counterclockwise.
- With the door closed, align the soffit plate with mounting holes in the frame. Fasten the soffit plate to the frame with flat head screws provided…. use spacer blocks 293S or 891, if required.

Thumbturn Hold-Open Feature
The Thumbturn Hold-Open feature is controlled by the knob located on the arm of the unit. Turning this knob clockwise will engage the Hold-Open mechanism and increase the Hold-Open force. Turning this knob counterclockwise will reduce the Hold-Open force and disengage the Hold-Open mechanism.
Friction Hold-Open Feature
Hold a door open to the opening angle desired and tighten the holder
adjustment- nut (wrench supplied) or use 1” Box or Open End wrench.
Unit Adjustment
Closing Power Adjustment
- Using the “Power Adjustment Chart” from Page 3, select the correct number of turns for the power adjustment shaft that corresponds with the installation. With a 1/8” hex-key provided, rotate the adjustment shaft fully 360° clockwise turns to the desired setting.
- After the closer has been installed and proper adjustments made to the sweep and latch, it may be necessary to readjust the spring power for good closing action.
Control Valve Adjustments
Closing Speed Controls (Figure 1A or 1B and 2.)
- Valve “S” Controls Sweep Range.
- Valve “L” Controls Latch Range.
Opening Cycle
The “Backcheck” valve controls the strength of cushioning in the Backcheck
Range. NEVER close this valve completely – it is not to provide a positive
stop. (see Figure 4 and Figure 5).
