Match your repair

Schlage F10 passage spring latch on a non-fire-rated interior timber door. The latch works normally with the door open; the door and hinges are sound. This example has a small vertical mismatch at the strike opening, correctable only within existing recess and screw-hole clearance.

Safety and stop conditions

  • Do not use this tutorial on exterior security, fire-rated, emergency-egress or electronically controlled doors.
  • Do not enlarge a latch pocket to a generic one-inch depth; the one-inch figure in Schlage’s broad article concerns a deadbolt.
  • No automatic filing, new pilot holes, mortise chiseling, deadlatch modification or strike replacement.
  • Keep the door open until free latch action is established and keep fingers clear of the closing edge.
  • Normal contact with the entry lip is part of spring-latch operation. Only a diagnosed opening-edge obstruction enters the adjustment branch.

Tools and materials

  • Matching hand screwdriver
  • Chalk that wipes off the metal finish
  • Pencil
  • Clean cloth
  • Doorstop

Before you start

  • Operate the handle while the door is open. A sticking latch is a mechanism problem, not proof of a strike problem.
  • Confirm no loose hinge leaf, dropped door, warped slab, rubbing edge or damaged frame. Refer hinge-related sag to guide 8 first.
  • Identify abnormal contact at the upper or lower strike-opening edge. A streak on the normal beveled entry lip alone does not establish a fault.

Repair steps

  1. Rule out a faulty latch

    Open an interior door with the matching Schlage passage latch. Turn and release the handle. Stop if the latch sticks or fails to spring out.

  2. Check the door first

    Inspect the hinges and door edges. If the door sags, rubs, or needs lifting, correct that problem first. Proceed only with sound hinges and a door that swings freely.

  3. Reveal the contact point

    Mark the latch tip lightly with chalk. Close gently and reopen. A mark at the opening’s upper or lower edge shows a height mismatch. A normal streak along the entry lip alone does not.

  4. Make a small adjustment

    Mark the strike’s starting position. Loosen its screws slightly and move the opening toward the marked edge, using only existing clearance. Stop if cutting or new holes would be needed.

  5. Secure the strike

    Hold the strike flat and retighten both screws by hand. Stop if a screw spins without gripping or the plate will not stay securely in its new position.

  6. Test the latch

    Wipe away the chalk. Close gently and check that the latch holds, then opens normally. Persistent rubbing, forced closure, or repeat movement needs a proper alignment repair.

Check the result

  • All stated open-door/closed-door checks pass without force, damage, looseness, binding or recurrence during the demonstration; otherwise report unresolved.

Common questions

Should I file the strike plate?

Not as the first step. Establish the cause and contact point first. This guide stops before material removal.

What if I must lift the door to latch it?

Check door support and hinge condition first; guide 8 addresses only sound fixings with loose screws.

Why will the strike not move?

Your plate, mortise or screw holes may have no adjustment allowance. Do not force it or enlarge the holes using this guide.
