At 29.4" high, the Tall Pet Gate with Security Armssecurely confines small, medium and some larger sized pets and is available in Wood and Wire construction. The security arms rest against the restrictedopening making it very difficult for the pet to dislodge or push aside the gate, particularly good for use on smooth surfaces. Another feature of the Tall Pet Gate is the rubber pads on the wood security arms that prevent marking walls. In addition, this gate is offered in two sizes, the Small Span extends from 27.6" to 50" Wide and the Large Span extend from 40.6" to 75.5" Wide. The support legs are 24.4" long and resist tipping and improve stability. They have rubber pads on the bottom to protect the floor and resist skidding. The gate has a sliding "adjustable-width" feature that makes them easily expandable to the width of your choice without using awkward hardware. The freestanding design means that no installation is necessary.
