Great price, but you'll probably need a vise, special tool or bring it to a shop to squeeze the end on your chains. 130678

These are hooks that I will be using to attach safety chains on a Car Dolly that I pull behind a Motor Home. The price was right, they were in stock and they arrived in a decent amount of time. I'll remember Etrailer for any future needs. 127390

Seems to me that the factory safety chains that come on trailers are rarely of a sufficient capacity to handle your trailer and all of it's valuable contents in the event of a coupling failure or an accident. These S-Hooks are a great start in beefing up my safety chain system to protect my ATVs and all my camping gear. 102328

Works exactly as it should. 100348

  • Width of the Opening on of the Curt S-Hook # C81820
  • The opening on the Curt S-Hook # C81820 measures 3/4 inches. Overall length is 4-1/8 inches. I attached a picture that shows this dimension as well.

  • Replacement S-Hooks for Trailer Safety Chains
  • We can offer you replacement S-hooks with keepers for your trailer's safety chains. You'll just need to find a suitable saw (or helper who can bend the S hook open) to remove the old ones. We have S-hooks in 7/16-inch size # C81820, 17/32-inch # C81830 and 3/8-inch # C81810. You can certainly use a clevis hook like # 6495-301-04 or a Quick Link such as # BX229-0512 if you prefer these over the S-hooks. Cutting your chains down to the correct length will not reduce their capacity so...

  • Is Brophy Safety Chain Mounting Bracket MB12 Compatible with Safety Chain 2118-605-04
  • The hook end of chain # 2118-605-04 will fit mount # MB12 but the opening in the chain links is too narrow for MB12 to fit. You would need chain # 1483-535-04. I tested this chain and the MB12 and they will work together. Or you could go with an S-hook with a keeper on it like # C81820 and securely hook onto the MB12.

  • How To Attach 7/16 Inch S-Hook To Safety Chains
  • Since the Curt S-Hook with Wire Keeper for Safety Chains and Cables, part # C81820 is made of 7/16 inch diameter zinc coated steel, I recommend using something like a vise or channel locks if available to crimp the end around your safety chains. If you do not have one at your disposal, you might consider taking it to your local garage or mechanic. They will likely have the equipment needed to get this s-hook attached to your safety chains. This S-hook is made of SAE Class lll steel...

  • Length of Curt Safety Chain with S-Hooks # C80031
  • Thank you for your recent purchase from etrailer. The Curt Safety Chain with S-Hooks # C80031 that you purchased has an overall length of 48-inches (including the two hooks) and an actual chain length of 40-inches as noted on the product page. Since I do not know how much additional length you require I suggest you take a look at TowReady # TR63035 which has an overall length of 72-inches. Or if you need only another inch or two you could add on Curt S-Hook with Wire Keeper # C81820...

  • Recommended Clevis Hook for a Winch and Safety Chains
  • I do have options for you but the Curt S-Hook with Wire Keeper part # C81820 is not going to be the best solution for your winch's cable/strap or safety chains. Instead, for the winch I recommend using a clevis hook like part # 6495-401-04 and for the safety chains I recommend using a clevis hook like part # 6495-301-04. The clevis hooks are a much better design for both your winch's cable/strap and safety chains. I have attached a review video of each clevis hook for you as well.

  • Size of Safety Chain Hooks on Draw Tite Hitch
  • I went to the warehouse to take a look at the safety chain hooks on Draw-Tite Trailer Hitch # 41946 and they measured about 1 inch wide and about 3/4 inches thick at its widest point. I took a look at a number of them and there was some slight variance in the thickness so it is highly likely yours is not exactly that width. It is not absolutely necessary for the spring latch (the catch) to snap shut because in the unlikely event the safety chains come into play the latch really isn't...
