QWORK G80 Alloy Steel Hammerlock Coupling Link Connecting Link, 1/2, Red Painted, 12000 lbs Working Load Limit,2 Pack

Perfect for trailer chains. Not sure why there are so many reviews that they are hard to install took literally five seconds each side.

These are easy to install but be prepared to really smack the pin through. I found it helpful to use a punch on the back side as a guide to help keep the shackle, pin, and center piece all lined up - then bang the hell out of the pin until it pushes the punch out of the way and settles into place.

Very happy with these. They fit my truck AND my trailers (small trailer and 6,000 lb boat). I bought a hook from a different manufacturer originally, only to discover that it was too thick for my trailer connectors.

These 12,000 lb links worked wonderfully with our 2022 F250 Ford truck. As others have mentioned many trailer safety chain hooks are difficult to snap on and unhook from the late model Ford truck trailer hitches. To simplify installation of these links we discard the pins and bushings, and use Grade 8 bolts to secure the two links together. Use: Two 3/8-24 TPI Grade 8 bolts (4 long). Two 3/8-24 TPI Grade 8 Nylon Insert Lock Nuts (Often called aircraft lock nuts). Four 5/16 (not 3/8) Grade 8 Flat Washers. (3/8 washers work but are loose and stick out on edges). All available at most good hardware stores and ranch supply stores. Install time: 3 minutes for both links. We have five late Ford trucks equipped this way. Super sanitary clean looking installation. One F150, one F250, and three F350s.

Used on choker 3/8 Coker chains for logging. So far they have held well to some tuff conditions

They were great, then I sold them with the truck!

Very easy to use. So far, have only used one, but the chain hasn’t failed in logging situations

They are great!!

Yes

I used these to build a small set of spreader chains they work very well.
