Great for those that transport both ATVs and snowmobiles, Caliber LowPro snowmobile trailer glides are designed specifically to increase traction for both vehicles and your own feet while protecting your trailer door or tilt trailer. They are manufactured from durable, high-density polyethylene plastic for maximum durability and longevity, with a low profile 1/8-inch glide and bushing height to prevent tripping and provide more clearance on telescopic sled deck ramps. This set includes 16 9-inch wide tracks to accommodate a 14-inch ski stance variance. At the edge of the glides, there is an outside channel that provides a place to channel the glides when used with custom manufactured extrusions or custom set-ups. Optional screw pockets along the edges come with fillers that can be removed as alternate fastening points when the glides need to be cut to accommodate custom lengths.
