Caliber Snowmobile Trailer Grips

These are high enough to keep aggressively studded tracks from marring your trailer floor. Hollow underside design allows for good drainage and drying out. I installed 8 packs of six in a large trailer with two ramps & flaps. My order was delivered in two parts, a delivery of six boxes followed by delivery of the last 2 boxes. One of the last 2 packs of grips was missing the screws. After hassles I am still waiting for the replacements. Suggest you check all boxes for hardware before starting the installation. Love the product itself. After purchase customer service via retailer/distributor could be better.
