Sherpa Kar9 Guard Rail Travel Barrier is a universal (fits virtually any car), fully portable and completely adjustable car safety pet containment system. The Kar9 beats all conventional barriers in quality, functionality, and style. We eliminated assembly damage common with compressing barriers. Our barrier does not need to be drilled in or clipped in like you will find with permanent barriers. The Kar9 remains solidly attached to the headrests stems present in virtually every auto vehicle. Made of high-resistance square steel tubing with solid galvanized steel 75 degree elbows and reinforced double thickness round tube extensions (1.8 mm); it also features solid built in adjustable clamps and a neutral color for reduced visual impact. Extremely compact packaging for shipping and storing. Sherpa Travel gives pet parents the best of all worlds: innovative products, stylish designs, and exceptional value with a variety of travel carriers, leads, mats, straps, to meet a pet's and pet parent's needs for travel. Sherpa products are designed to meet child safety standards. Please read all packaging instructions, warnings and cautions upon receipt. Packaging contains small parts, discard after opening.
