Most bathroom stall doors have a two-tier hinge configuration that is clearly visible in the form of separate upper and lower sections. Installing such doors into bathroom stalls requires a systematic approach to make the entire process an easy combination of some uncomplicated procedures.
Step 1 - Drill a Top Hole
Drill one top hole for the top hinge of the stall door with a 1/4 -drill bit, 13 1/4inches from the top of the pilaster.
Step 2 - Drill a Bottom Hole
Drill one bottom hole for the top hinge in the upper portion of the door with a 1/4-drill bit, 1 1/2 inches below the top hole.
Step 3 - Drill into Door
Drill the top hole and bottom hole for hinge fittings in the lower portion of the door using the 1/4-drill bit. The top hole for the bottom hinge should be drilled 68 inches from the top of the pilaster and the bottom hole should be 1½ inches below the top hole.
Step 4 - Secure the Top Hinges
Use two thru-bolts & barrel nuts for securing the upper pilaster hinges.
Step 5 - Secure the Bottom Hinges
Insert nylon bushing into the bottom space of the top hinge. Use two thru-bolts for securing the lower pilaster hinges.
Step 6 - Align
Set the door against the bottom hinge and press lightly upon it to ensure the hinges are properly lined-up. Align the upper pin holes with respective holes of the top hinge. Push in the hinge pin and hammer lightly. Use 3/8 x 1 inch cap bolts for fastening the bottom hinges.
Step 7 - Check Alignment
Try to move the door. The door should stay steady at all angles. Tighten the bolts using a wrench.
Step 8 - Install the Knob
To install the door knob, push-in the inside portion of the chosen latch. Start aligning the tooth of the latch along with the internal escutcheon plate. Compress the latch and the plate together, pushing-in the knob. Tighten the manufacturer’s screws for fitting the knob.
