The Summer Infant Sure And Secure™ Tall Walk-Thru Gate is an ideal choice when containment is needed in busy areas of the home. This extra-tall gate is 36 inches high when mounted. Depending on your needs, the gate can be mounted with hardware or held in place with pressure. The door swings closed and locks automatically, eliminating the possibility of someone forgetting to close that gate as they walk through. (Here, we're talking about you. It's a simple mistake, and you don't want to make it.) Because of the 5- and 10-inch extensions, this gate will fit most openings up to 47.5 inches wide.
