Quick answer
A gate extension kit lets you safely widen a pressure-fit stairgate to fit openings wider than the gate's standard width. The Fred Safety Pressure Gate Extension Kit, for example, adds 7 cm per extension and can be stacked up to three times per side for a maximum width of 124 cm.
When an extension kit is the right fix
Not every wide opening needs a custom gate. If your gap is within 7–28 cm of the gate's standard width, a gate extension kit is usually the simplest and most affordable solution. It works best with pressure-fit gates because the extension pieces slot directly into the gate frame without tools or drilling.
If your opening is more than 28 cm wider than the gate, you may need a wider gate or a different mounting method. Extension kits also cannot be used with screw-fit gates unless the manufacturer specifically supports them.
What to check before buying
Measure the total width of your opening first. Then check the maximum width your gate can reach with extensions. For the Fred Safety Pressure Fit Wooden or Clear View gates, you can add up to three extensions per side, bringing the total to 124 cm. Each kit adds exactly 7 cm, so plan how many you need.
Also confirm that the extension kit matches your gate model. Pressure-fit extension kits are not universal; they are designed for specific gate brands and types.
How to install a gate extension kit
- 1. Measure the opening width: Use a tape measure to find the exact width of the stairway or doorway at the point where the gate will sit. Write down the measurement and compare it to your gate's standard width. Common mistake: measuring at floor level only. Always measure at the height where the gate will be installed, because walls can taper.
- 2. Calculate how many extensions you need: Subtract your gate's standard width from the opening width. Divide the remainder by 7 to find the number of extensions required. Each extension adds exactly 7 cm. Round up to the nearest whole number. Checkpoint: do not exceed three extensions per side. If your calculation needs more than three, the opening is too wide for this solution.
- 3. Attach the extensions to the gate: Push the extension piece into the side rail of the gate—one on either side if needed. The extensions click into place without tools. Ensure they are fully seated and flush with the gate frame. Common mistake: forcing the extension in at an angle. It should slide straight in. If it does not, check that you are using the correct side for the extension.
- 4. Fit the gate into the opening: With extensions attached, position the gate in the opening. Adjust the pressure-fit mechanism (usually a twisting knob or tension rod) until the gate is snug and level. Test that it cannot be pulled free. Checkpoint: after tightening, give the gate a firm push near each corner. If it shifts, the tension is too low. Tighten slightly more until the gate is solid.
- 5. Test the gate operation: Open and close the gate several times. Ensure the locking mechanism engages fully on both sides and that the gate swings freely without scraping the wall or floor. Common mistake: assuming the gate is secure because it feels tight. Always do a full open-close cycle to confirm the lock catches properly.
