Safely secure your SUP or kayak to the top of your care using these straps. Each strap is made of nylon webbing and uses a cam buckle to tighten. The buckles are foam padded to prevent scratching and this type of strap is preferable to ratchet straps which are harder and more time consuming to set up as well as easily over tightened which can lead to cracks and damage to your equipment. Sold individually. Buy 2 to secure both the front and back of your board or kayak.
