Crown Pet offers the Small/Narrow Span or the Large/Wide Span 21-Inch Freestanding Wood/Wire Pet Gate designed to match any décor, while comfortably and safely securing pets. Constructed of Eco-friendly Rubberwood, a durable hardwood, the Chestnut finish is stained and lacquered just like fine furniture to ensure lasting beauty. An innovative feature of the 21-inch Pet Gate is the security arms that rest against the restricted opening making it very difficult for you pet to dislodge or push aside the gate, particularly good for use on smooth surfaces. Rubber pads on the wood security arms prevent marking walls. The durability of Mortise and Tenon construction adds strength to the gate. Long support legs, (19 inches) on the 21-lnch Large model are longer than on most other gates therefore resist tipping and improve stability. The freestanding design requires no installation and you can use it in any area of your home, yet easily folds flat for storage or transport to another location. The Crown pet gate has a sliding ""adjustable-width"" feature that makes it easily expandable to the width of your choice without using awkward hardware or tools! Decorative yet functional, Crown Pet Gates are stronger and more stable than most gates on the market. At 21"" high, this gate is easy to step over yet securely confines small and medium sized pets. The Large/Wide span fits openings from 40"" to 74.5"" wide and the Small/Narrow span fits openings from 27" to 48.75" wide.
