This ¾ inch X 2 foot heavyweight polypropylene spring buckle strap can be used to replace the ball bungees on the rear tire holder of the tadpole carrier. It takes a little longer to secure, but is stronger and will last longer. Ideal in tougher conditions behind a motor home or camper and on long trips. In most situations only one will be necessary. This is a handy strap with many uses. We are adding this as a replacement for the ball bungee.
