"The Petyard Passage Barrier/Pen with Wall Mount Kit by North States is a safe, dual-purpose containment system which features an exclusive swinging door for pets and can act as an extra-wide barrier with the use of the included wall mount kit. The 9.5 x 8 door swings freely allowing your dog the freedom to come and go as they please and also locks for containment offering you peace of mind. Perfect for households with puppies or multiple pets and the ideal solution for homes with open floor plans or large spaces that need blocking off. Fits openings from 38 1/2 inches to over 16 feet wide. Configure to Your Space: When used as a barrier, the hardware should be mounted into solid materials such as wood, metal or a stud behind sheet rock. To accommodate different sized openings, add or remove panels up to six for all stages and phases of your pet's life. The hinges on the Petyard allow you to move the panels independently for the perfect fit. Stretch the panels straight across or at an angle, the choice is yours. The wall mounts secure the panels from wall to wall and fit over crown molding with ease. Skid-resistant pads prevent scratching & slipping and help to keep the barrier stable when on hard surfaces. Not for use at the top of stairs. Free-Standing: Position as a hexagon and your extra-wide barrier instantly becomes a free-standing petyard, creating a safe space for use indoors or outdoors. In this shape, it encloses up to 18.5 square feet - that's 5 1/2 feet corner to corner. Weather resistant and portable, the Petyard Passage can be used just about anywhere. Proudly made in the USA."
