Mortise Nut and Screw Detail

Appropriate mortise nuts and screws will be supplied based on door thickness.

Door construction must provide a bridge type reinforcement to prevent the door rail from collapsing when screws are tightened.

If distance between door stop and center of mortise nut head is less than 7/8" (22mm), stop must be cut to clear head or head must be recessed.

Closer Adjustments

Use provided hex wrench to turn valves. NEVER force valves out of closer. NEVER completely close backcheck valve. NEVER use backcheck as a door stop.

Door must be open (only a few inches) to adjust spring closing power. Use 3/16" hex wrench to turn screw. Do not use a power drill. Warranty will be void.

If interior doors do not have to comply with ADA requirements, exterior door settings are recommended. Where strong drafts exist, increase spring power as needed by turning spring adjustment screw clockwise. If necessary, reduce spring power by turning screw counter clockwise.
