The High Latch Goes Above Her Reach: Install It Start to Finish, Then Test the Catch

The latch you have in mind is small, and that is what makes it easy to rush. A hook-and-eye or a slide bolt set high on the inside of a door takes one evening to mount and a few minutes to test, but the test is where most of the work is. Go slowly, and check each step before you move to the next one.

Before you drill

Stand inside the door at the time of day she usually tries to leave, and reach up with your own hand. Hold the eye of the hook where your hand stops, and mark the spot in pencil on the frame. Then look at the spot from her side of the door, and ask whether it is still a place she could see and reach if she stood on a chair. Choose the hardware last, after you have the spot.

Check your house's exit rules before you commit. A latch that stays on the inside has to open with one hand, without a key, a tool, or a twist that someone in a hurry might not manage. A door that serves as a way out in a fire should never depend on a latch you cannot open quickly. Ask your local fire department or building office what they expect for that door.

Mount it in order

Fix the eye or the bolt keeper to the door frame first, not to the trim. Use screws long enough to reach the framing behind the trim, and drill pilot holes so the wood does not split. Close the door, then mark on the door where the hook or bolt lands. Mount that half the same way, pilot-drilled, with screws that bite into solid wood.

Test the catch

Close the door and drop the latch. Pull hard on the handle from the outside, then push from the inside. Lift the latch with one hand, without looking for a tool, and open the door. Repeat that five times. If the hook pops free, the screws are in trim or the eye sits too shallow. If the hook binds, the mark was slightly off, so move the eye about a quarter inch and test again.

Keep it working

Once a month, check each screw with a screwdriver, and look at the wood around it for a split or a soft spot. Wood that moves is a sign the latch will fail under a hard push. If the frame is soft, the fix is a longer screw into solid framing or a new frame piece, not more force on the latch.

Decide who does the drilling

If you do not have a drill and a level, ask a handyman or a hardware store for a written scope before anyone starts. Ask whether they will mount to the frame or to the trim, what happens if the frame splits, and who comes back if the latch will not catch. Compare the answers on paper, not only by phone.
