Frequently Asked Questions
Are pressure-mounted gates safe to use at the top of stairs?
Pressure-mounted gates are convenient but not recommended by safety experts for top-of-stair installations unless the gate can be hardware-mounted with screws or used with manufacturer-supplied wall cups anchored into studs. For stair tops, use a hardware mount or a mounting kit specifically rated for stairs.
Will a banister mounting kit work with any gate brand?
Many universal banister kits are designed to accommodate a wide range of pressure-mount gates, but compatibility depends on gate frame dimensions and spindle diameter. Always check the kit's listed spindle diameter limits and gate attachment method before purchasing.
How do I measure my opening to pick the right extension?
Measure the narrowest point where the gate will sit, including baseboard and trim. Compare that measurement to the gate's base range, then add the extension sizes to confirm the combined width fits. If in doubt, choose a gate or kit that includes multiple extension panels.
