The First Years Slimline GateThe Slimline Gate adds a touch of fashion with the safety features you expect and need in a gate. This gate is hardware-mounted and can be set to open in one direction for use at the top of stairs, or set to open in both directions when installed between rooms. The Slimline Gate has a secure three-step locking mechanism that features a simple one-handed operation for you, but is too difficult for a child to open. It has been designed with your child's safety in mind!
