opening force guidelines.
• ADA compliant closers may not latch doors, manufacturer does not guarantee latching on lower opening
force settings.
• A separate Rixson Surface Checkmate® or other door stop, supplied by others, is strongly recommended to
avoid damage to door closer and adjacent property.
• Doors should be hung on ball bearing or anti-friction hinges/pivots. Door must swing freely. For other hanging
means a special layout may be required, consult factory.
• Door and frame must be reinforced for attaching screws.
• All dimensions are given in inches (millimeters).

proper frame clearance that this anchor hole is
positioned within 1/32" of true plumb alignment
with the top jamb portion pivot point.
4. With open side up, place drop-in anchor into oor
hole. If necessary, tap lightly with hammer until
anchor is at bottom of hole.

carefully t door onto bottom pivot at a slight
angle. (Figure 6)
3. Tip door into vertical position aligning frame
portion pivot stud to door portion hole.
(Figure 7)
4. With top pivot stud aligned with door portion
hole, use a athead screwdriver to turn pivot
