Frequently Asked Questions
Can I use a pressure-mounted gate at the top of stairs?
Manufacturers typically recommend hardware mounting at the top of stairs because screws anchor the gate more securely to the wall. Pressure-mounted gates are better suited to doorways and low-traffic openings where permanent mounting isn’t desired.
How do I measure for an extension or extra-wide gate?
Measure the clear opening between the surfaces where the gate will attach, including any baseboard or molding. Compare that measurement to the gate’s stated fit range and add any needed extension pieces; choose a gate with some adjustability to account for uneven walls.
Are pet doors safe on baby gates?
Lockable pet doors can be convenient for small pets and generally safe if the opening size and lockability match your needs. Ensure the pet door height and width are suitable for your pet and that the main gate remains fully secure for children when the pet door is open or closed.
