"Caliber Trax Grabber 23060 attaches to a snowmobile trailer deck for increased rear track loading traction and provides surface protection from spinning snowmobile tracks. The low-profile design sits flush with snowmobile ski glide protector tracks and features lug placements designed to engage 2.5"", 2.86"", and 3"" pitch tracks. Great for loading snowmobiles with paddle or studded tracks."
