Interior Passage Sets

Unwrap all components, laying them within easy reach. You will need a screwdriver, ruler, and nail polish or threadlock.

Door Preparation:
(If door is pre-drilled, skip this step) Choose a location for the doorknob to install, approx. 36”-38” from the floor, or centered in a pleasing location. Using a hole saw, drill a 2 1/8” hole through the door, with a centered backset of 2 3/8”. Edge bore a 1” hole into the door, approximately 3 3/4” deep, centered as shown. Insert latch into the bored hole and, keeping it perpendicular to the floor, use a sharp awl or razor knife to scribe a line around faceplate. Remove the latch and use a chisel to cut an approx. 3/16” deep mortise, so that the latch face will lie flush with the door edge.



Install the Latch:
Install latch into the door with the rounded part of the latch tongue facing the door jamb. Tighten screws securely.




FOR LONGPLATES:
Gently back the set screws out of each doorknob approx. 1/2 way, or until they do not protrude through the spindle hole. To be sure that the spindle is centered in the latch, unscrew one knob approx. 1/4” - 1/2”, depending on the thickness of door. Remove the other knob completely.
You should now have one doorknob still on the spindle and one loose doorknob. Holding the knob which is on the spindle, slip the spindle through one of the door plates and guide the spindle through the square hole in the door latch. Slide the other door plate onto the protruding spindle and screw the remaining knob onto the spindle, snugly to hold plates in place.



Use a ruler to make sure that the plates are parallel to the edge of the door. Give the knobs a bit of a wiggle to align them and keep them from binding against the plates. Screw the top screw(s) into one door plate, then the bottom screw(s), and again check your alignment. Follow with the plate on the other side. Now, unscrew the doorknobs about 1/2 turn or just until they turn freely. If all is still aligned and the knobs turn easily, screw in any remaining wood screws.




FOR ROUNDPLATES:
We have provided two lengths of machine screws to mate the backplates. Choose the shorter machine screws for 1 3/8” thick doors or the longer screws for 1 3/4” thick doors. If you need a different length than those provided, call 1-800-522-7336 for technical assistance.



Loosen set screws and remove both doorknobs from the spindle. Center the spindle in door latch. Slide the threaded backplate over the spindle on the outside (most visible) side of the door. Slide its mate (with screwholes) onto the other side. Screw the backplates together, snugly but not too tight. Screw one doorknob onto the spindle, keeping the spindle centered. Now screw on the second knob, bringing it up snugly, allowing the backplates to align themselves. Tighten the backplate screws. Now, unscrew the doorknobs about 1/2 turn or just until they turn freely.




Finishing the Knob Installation:
Screw in all set screws carefully, making sure that they tighten against the flat part of the spindle (a slight wiggle can help to set them in place). Try the doorset, making sure that everything works smoothly. Lastly, remove each set screw, one at a time, and coat threads with fingernail polish or threadlock. Replace each.

Installing the Strike:
Placing the strike in the correct position is very important for proper doorset function. Using a small piece of carbon paper, close the door so that the latch rubs the black carbon onto the door jamb. Repeat until a black smear is clearly visible, showing the path of the latch tongue. Center the strike over the black mark. Mortise for strike similarly to the procedure used for the latch face. Use a drill to cut the hole for the latch tongue. Install strike.
