Frequently Asked Questions
How do I measure for a baby gate extension?
Measure the clear opening from wall to wall at the height where the gate will sit, and note any trim or molding that reduces usable width. Compare that exact measurement to the gate's stated fit range; if you're near the edges of the range, favor a kit with larger or multiple extensions.
Can I use pressure-mounted extensions at the top of stairs?
Manufacturers generally advise against using pressure-mounted gates at the top of stairs because they can shift under load. For stair tops and other fall-risk locations, choose a model that can be hardware-mounted and install it using the included wall hardware.
Are extension panels universal across brands?
Most extension panels are brand- or model-specific and use matching pins or connectors. Always confirm compatibility—Toddleroo extensions, for example, only fit certain North States gates—otherwise you risk improper fit and reduced safety.
