✅ FIT - Xtra fits 9” round metal feet on many Class A and 5th Wheels RVs. Please verify size (9”) before ordering. | ✅ PERMANENT - SnapPads can be installed in minutes but will stay on forever. Snap them on and rid yourself of all your leveling hassles. Say goodbye to crawling under your rig every time you set up. | ✅ STABLE - SnapPad increases stability in 3 ways: a larger footprint, more vibration dampening, and by conforming to uneven terrain like gravel. ANTI-SLIP - SnapPads are made from durable rubber that grips any terrain. No more popping jacks or slipping in high winds or on slick surfaces. | ✅ RUGGED - Our process uses recycled tire crumb, high strength resin, and a 100+ ton press to make SnapPads extremely durable. SnapPads are engineered to be resistant to UV exposure, water, heat, oil, tar, mud, and other environmental hazards. Protects your metal landing feet from damage. | ✅ ENVIRONMENTALLY FRIENDLY - Made in the USA from recycled American tires. WARRANTY - Two year manufacturers limited warranty.
