The 23" tall Position and Lock Tall gate that fits openings from 26-42" helps parents keep their children safe from common household dangers. Not only is this classic pressure mount gate easy to install as there is no hardware required and robust non-marring rubber bumpers. Also, the locking bar is marked and notched for easy installation and re-installation. If a little extra height is what you're looking for, this gate is a great choice as kids will have a hard time surmounting this obstacle. It also is wonderful to use with pets and dogs that can jump over smaller gates. Finally, the sturdy wood frame and vinyl-coated mesh are durable and secure leaving you with a feeling of assurance that your child is away from harm. NOTE: Per BabyQuip policy, we don't install gates. Furthermore, pressure-mounted gates are not approved by the manufacturer for placing at the top of stairs.
