Before ordering a stairgate, check the opening, mounting surfaces and the exact location where it will be used. Getting these details right helps you choose a compatible gate and avoid unsuitable extensions or improvised fixings. This guide is a buying and preparation checklist, not a replacement for your gate's installation manual.
1. Confirm the intended position
Decide whether the gate will be fitted in a doorway, at the bottom of stairs or at the top of stairs. Check that the exact model is explicitly suitable for that position. Follow the manufacturer's requirements for stair placement, fixing method and opening direction; do not assume a gate approved for a doorway is approved for stairs.
2. Measure where the fixings will sit
Use the product's fitting diagram to identify the mounting points, then measure the clear opening at those heights. An opening can be narrower near a skirting board or wider higher up. Record any uneven surfaces, sloping walls, posts or mouldings that affect the installation.
Do not rely on the door's nominal size or a single measurement across the floor. If the product information does not show where to measure, ask the manufacturer before ordering.
3. Compare the complete width range
Check the gate's stated minimum and maximum opening widths. If extensions are needed, confirm the approved combination for your exact measurement. Include required adapters in the manufacturer's calculation and do not exceed the permitted overall width.
Keep the measurement with the product name and model number so you can recheck compatibility before checkout.
4. Check mounting surfaces
Inspect the walls, frame or posts where the gate will attach. The surface must be suitable for the product's required fixings. Rounded bannisters, weak surfaces and uneven frames may need an approved adapter or a different gate. If you are uncertain about the structure or suitable hardware, seek qualified installation advice.
5. Plan access and trip-hazard checks
Check the walk-through width, opening direction and any threshold bar. Make sure the gate can open as permitted without obstructing a stairway or walkway. Consider how adults will use it while carrying a child, but never compromise the required mounting position for convenience.
6. Install from the exact manual
Read the complete instructions before starting and use all required components. Some pressure-fit gates need fixed wall cups or other hardware. Do not omit these, substitute unapproved parts or modify the frame. If instructions are missing, obtain them from the manufacturer before use.
7. Check the gate before relying on it
Complete the manufacturer's installation checks, including the stability of fixings and full engagement of the latch. Do not use a gate that shifts, fails to close properly or has missing or damaged parts. An automatic-closing feature does not remove the need to check that the latch has engaged.
Everyday stairgate checklist
- Close and secure the gate after passing through.
- Inspect joints, mounting points and the latch regularly.
- Recheck the installation after moving or adjusting the gate.
- Keep toys and furniture that could enable climbing away from it.
- Follow the product's age and developmental limits.
- Continue supervising your child; a gate is not a complete childproofing solution.
Frequently asked questions
What if my opening is between two listed sizes?
Ask the manufacturer which approved gate and extension combination, if any, covers the exact width. Do not force a gate into place or use makeshift packing to bridge a gap.
Can I fit a gate against a bannister?
Only if the gate instructions allow the arrangement and you use any required approved adapter. Post shape and structural suitability matter as well as width.
Can I reuse a gate in another room?
Check the new opening and approved location from scratch, then reinstall according to the manual. Previous use in one position does not establish suitability elsewhere.
What if the gate no longer closes correctly?
Stop relying on it until the cause is resolved using the manufacturer's guidance. Check for looseness, movement, wear or damage rather than forcing the latch or altering the gate.
