Step 1: |
To locate pivot on frame, hold combination square in corner of frame and place installation template against square exactly as shown, spot hole centers with center punch. |
Step 2: |
Drill holes required as per schedule. Note: If material thickness is not sufficient or when hollow metal frames are not reinforced, use #14 x 1 1/4" Type A sheet metal screws. Wood Frame: Drill pilot holes and install wood screws. |
Step 3: |
With door in place, check to be sure that hinges are firmly attached and there is proper clearance between door and frame at all sides, including bottom of the door. If door tends to sag away from hinge jamb at top, drive wedges between frame and door at opposite strike side and re-align hinges until door is properly positioned to swing free. |
Step 4: |
Place door portion of pivot (with pivot in place) on door and move into position so the pin enters bronze bushing. When properly aligned with lower part making light contact with bearing flange, hold firmly in place parallel with head of door and mark hole locaitons. |
Step 5: |
Repeat drilling instructions noted in Step 2 for metal doors, drill .2010 diameter holes (No. 7 drill) for 1/4-20 machine screws and tap hole. Note: Use two sleeve bolts furnished with each pivot. Use as required for hollow metal or mineral core doors (See Fig. 3). Drill 1/4" hole through door. Enlarge hole on side opposite pivot to 3/8" diameter for sleeve bolt. |
