Patented push-button retractable ratchets are easily operated by pulling the web out to the desired length and then ratcheting until tight. To release webbing from the locked position, simply push release button. Excess webbing is stored in the center housing to prevent web from flapping in the wind. This feature also keeps the straps clean and free from oil and dirt. S hooks are vinyl-coated to prevent scratching. 1200 lb. Breaking Strength 400 lb. Working Load Limit. 2 per pack.
