How to install a hardware-mounted baby gate
A hardware-mounted gate is screwed to the wall or banister, so it cannot be pushed out. It is the kind to use at the top of stairs. It should swing away from the stairs, and its bottom rail must not create a trip step.

Parts to check first
Before you start, lay everything out on a soft surface (the flattened box works) and check it against the parts list in your manual.
- Gate panel
- Hinge-side and latch-side wall brackets
- Screws and wall plugs for your wall
- Banister adaptor kit, if needed
- Extension pieces, if needed
Step by step
Step 1: Measure the opening and check the gate, with any extensions, fits the width. At the top of stairs, choose a gate the maker says is suitable for that position.
Step 2: Scan the wall or post for pipes and cables, and find solid timber or masonry to fix into; use a banister kit rather than screwing into a round spindle.
Step 3: Hold the hinge-side bracket at the height the manual gives, level it, mark the holes, drill and fix it with screws suited to the wall.
Step 4: Hang the gate on its hinges and set it so it will swing away from the stairs, never out over them, and block it from opening that way if the gate allows.
Step 5: Close the gate, level it, mark and fix the latch-side bracket so the latch engages fully.
Step 6: Adjust the hinges until the gate closes and latches every time, and the gap under it is within the manual's limit.
Step 7: Push and pull hard on the closed gate at the top to check that the brackets and screws do not move.
Common mistakes
- Using a pressure-fit gate at the top of stairs.
- Fitting the gate so it swings out over the stairs.
- Fixing screws only into plasterboard, which can pull out.
Safety notes
- At the top of stairs, use a hardware-mounted gate only and fit it at the top of the stairs, not a step down.
- Check the wall for pipes and cables before drilling, and get help from a professional if the wall or banister is unsuitable.
- Remove the gate when your child can climb it or reaches the maker's age limit.
This is general guidance for this type of product. Your product's own manual comes first: follow its order, fittings and torque values where they differ from this page.
