Ken's bolt on Hooks. Thanks Ken, your products and business plan continue to amaze me. My locking grab hooks will be on my go to # 1 chain today. The two quick disconnect ends will replace two old leakers on a used 54" plow and I know they will work. The price with shipping was less then I could get from my local shop, one block away from my home. His quality is half yours and he acts like he is doing me a favor by selling to me. (Small order). Add in a rebate for shipping, (smaller box) and now make it fast to me and you have a perfect storm. Quality, price and speed to me. What more can a customer want ?
