5/16" Quick Link, Zinc, Heavy Duty, Peerless Chain Company, #4721338

We put up new clotheslines after my old ones got wrecked. The new coated cables have loops at each end. I used turnbuckles to attach them at one end, and S hooks at the other. The turnbuckles ended up being too long so I replaced those with S hooks. While this was an easy fix, the wind would flip whatever was hung on the clotheslines until the S hooks became unhooked, my items ended up on the ground and a search for the S hooks began. Enter Quick Links!! Although the smaller ones I bought first don't open far enough to attach to the I-bolts on my crossbars, this size is perfect! And I'm keeping the smaller ones, they were inexpensive and are bound to come in handy for something. Picture of this item and the smaller one I bought first.
