The Regalo Retractable Safety Gate is a simple and effective way to protect your baby and home. Made of high-quality mesh, the retractable baby gate slides to fit openings up to 50? and stands 30? tall. The hardware mount retractable gate can be installed within an opening or on the outside of the opening. Once installed, pull the PVC mesh barrier to the other side of your opening and hook into the mounting hardware. Use the easy turn-to- to lock the gate in place. An indicator window easily allows you to see whether your gate is locked or unlocked.
