Installation Procedure
Frame Preparation
1. With the hinge open, place the hinge frame leaf against the frame rabbet. Position the top of the h
inge 1/8” (3.2mm) below the
header. Allow 1/16” (1.6mm) between the frame stop and the edge of the hinge.
2. Mark and center punch the screw hole locations.
Accurate location is important for proper hinge installation.
3. For metal frames 14 gage or less (
≤.080”/2.0mm) it is not necessary to pre-drill pilot holes if using the self-drilling screws provided.
For metal frames 12 gage and over (
≥.093”/2.3mm) drill and tap all mounting holes for #10-24 threads prior to installing the screws.
For wood frames, pre-
drill pilot holes using a #25 (.149”/3.8mm) bit.
4.
Do not attach the hinge to the frame at this time.
Door Preparation
1. With the hinge open, place the hinge door leaf against the edge of the door. Position the integral corner guard fully against the
‘push’ face of the door. Position the top of the hinge flush with the top of the door.
2. Mark and center punch the screw hole locations.
Accurate location is important for proper hinge installation
.
3.
For wood doors, drill pilot holes using a Z (.413”; 10.5mm) bit to a minimum depth of 1-3/8” (35mm). For reinforced metal doors, drill
pilot holes using a 25/64” (9.9mm) bit and tap for 7/16”-20 threads.
4.
Using a 3/16” Allen wrench, screw a 7/16” Adjustment Stud into each hole. Insert each stud until it is flush with the edge of the door.
The studs are designed for a tight friction fit in the holes so they will not turn when the mounting screws are being tightened. If the
Adjustment Studs turn too freely, apply LOCTITE
(for threaded joints) to the stud’s external threads during installation.
Hanging the Door
1.
Place the separate Protective Corner Guard component into position on the door edge and fully against the ‘pull’ face of the door.
Place the hinge door leaf over it making certain the integral corner guard is
fully against the ‘push’ face of the door. Install a #10
machine screw in the top two and bottom two hole locations only and fully tighten. Do not install the remaining screws in the door
leaf at this time.
2. Position the door (with hinge attached) at 90
to the frame. Attach the hinge to the frame rabbet. For metal frames, use the #10
self-drilling screws provided (recommended driver speed 1,900-2,500 RPM). For wood frames, use the #10 wood screws.
3. Make a gentle trial swing. Carefully check for proper swing and door clearances.
Adjusting the Door
1. If lateral adjustment of the door is required due to excessive or uneven door/frame clearance, make adjustments using either the top
two and/or bottom two screws installed in the door. It is not necessary to remove the hinge from the door to make adjustments.
2.
Remove one of the two screws and insert a 3/16” Allen wrench through the hole into the Adjustment Stud. It may be necessary to
slightly loosen the second screw while rotating the Adjustment Stud outward to the desired position. Then adjust the second Stud in
the same manner. Re-insert and tighten the #10 machine screws when complete.
3. Make any necessary adjustments at the other end of the hinge in the above manner until the proper door fit is achieved.
4.
Using a 3/16” Allen wrench, adjust all remaining studs until each rests against the back of the hinge leaf.
5. Install #10 machine screws into all remaining holes and tighten.
6. Make a gentle trial swing. Carefully check for proper swing and door clearances.
