Frequently Asked Questions
How high should a gate be to keep a toddler safe at a patio or balcony door?
Aim for at least 30" height for general toddler safety; if you have a particularly active climber or want more margin, a 37" option (like some retractable models) reduces the chance of a child climbing over.
Should I use pressure mount or hardware mount for a balcony gate?
For balcony tops and stairs, hardware mounting is recommended because it anchors the gate to the structure and resists strong pushing or climbing. Pressure mounts are fine for ground-level patio doors and renters, but consider hardware if safety consequences are greater.
Can retractable mesh gates be used outdoors or on patios?
Many retractable mesh gates are designed for indoor and covered outdoor use and feature weather-resistant mesh and supports, but permanent outdoor exposure (rain/sun) can accelerate wear. Check the product’s outdoor-use guidance and prefer reinforced mesh if pets will scratch at it.
