Video Transcript for Curt Tie Down Straps C81970 Review

Today we're going to be taking a look at the Curt clevis hook with a spring loaded safety latch. This heavy duty clevis hook lets you quickly and easily connect a chain to any application. It's going to come with your keeper pin and clip that provides a steadfast connection point. The spring loaded safety latch is going to keep the hook from accidentally disconnecting. That's a really nice design. The unit's made from a forged steel construction that's very strong and durable and it has a nice yellow zinc coating that's going to do a great job at resisting rusting and corrosion. This is rated with a capacity of up to 40,000 pounds.

You'll notice that on the hook itself, there's going to be a stamp that says G70. That's grade 70. There's also going to be a stamp that says 7/16 inch. That's the steel. That measurement's actually taken from this point here to this point there.

If we measure just the thickness of that little area right there, that's where we get the 7/16 inch mark from. Now, the measurements are going to vary depending on the area of the hook. We'll go over a few basic measurements just to help determine if this is going to work good for you or not. The opening size that we have, so if we open the latch all the way and take a measurement of that opening, that opening's going to give us a measurement of about 1 1/8 of an inch. That's just basically measuring the gap that we have right here.

The diameter of the pin, that's going to be 1/2 inch diameter pin. The opening at the pin measuring right here where my finger is, and it's going to give us a measurement of about 5/8 of an inch. Then, you're going to have about 9/16 of a gap, 9/16 of an inch when it comes to the gap above the pin there. You can see at the point, it's a little bit more narrow. In the middle, it's a little bit thicker, so in the middle, that's going to give us a measurement of about 1 3/4 of an inch from that point there to there. The point itself, that's going to give a measurement of about 7/16 of an inch, right in that area.

You can see it's a very narrow design. It's going to be about 7/8 of an inch thick, but again, forge steel construction, nice strong durable design, and basically the clevis hook is designed to be attached to a chain, that way you can connect a chain really to any application. That's going to do it for today's look at the Curt clevis hook with the spring loaded safety latch.

  • Safety Chains and Hooks for Curt Ball and Safety Chain Loop Kit
    To fit your Curt Ball and Safety Chain Loop Kit # C60618, you need hooks that can fit over the roughly 1" wide top and 3/4" sides. You could use the Curt Clevis Hook # C81980 which has a 1-1/4" opening. This hook has a lot more weight capacity than you need but should fit just fine. I've added a link to a video review for you to take a look at.

  • Safety Chain Hook Recommendation for a 2011 Chevy Silverado 2500HD
    I have a clevis hook that may work. Take a look at part # 6495-401-04 . This hook has a working load limit up to 5,400 lbs and the pin that connects through the chain is 7/16 of an inch in diameter. The Curt Clevis Hook, # C81970 , has a 40,000 lb weight capacity and the pin that connects through the chain is just over half of an inch (.52 inches) in diameter. This hook was designed for heavy-duty applications such as gooseneck trailers, but it may work with your trailer if the chains...

  • Should Safety Chains Hook to a Trailer Hitch from the Top or Bottom
    I have seen it done both ways. Ultimately, the important thing is to make sure the chains are crossed beneath the trailer tongue so if the trailer pops off of the ball the cables will catch the tongue and keep it off of the ground. Since the Curt hook, # C81970, has the keeper on it, the chains would not fall off if you hooked them to the hitch from underneath.

  • Curt Clevis Hook with Spring Loaded Safety Latch - 7/16 - 40,000 lbs Item # C81970
    The Curt Clevis Hook with Spring Loaded Safety Latch - 7/16 - 40,000 lbs Item # C81970 that you referenced is Grade 70, the attachment pin is 1/2 inch diameter, and the opening where the chain would slip through and the pin would hold it in place measures 5/8 inch. So basically the thickness of your chain link would need to be less than 5/8 inch and the width of the link opening would need to be more than 1/2 inch.

  • Opening Dimension of Clevis Hook For Safety Chain Connection To Trailer Hitch Safety Loops
    The Curt Clevis Hook with Spring Loaded Safety Latch - 7/16" - 40,000 lbs # C81970 will work with most systems. Without knowing the hitch or the diameter of the safety loops, I can't confirm a fit other than to tell you the opening of the hook is 1-1/8 inch. The vast majority of 2, 2-1/2, and 3 inch trailer hitch receivers will allow this 7/16 hook with spring to work. I've attached a video to assist as well. Let me know if you need further assistance.

  • Will Curt Clevis Hook Attach to Curt Class V Hitch?
    The Curt 81960 clevis hooks you referenced have a 1" opening, and the safety chain loops of Curt hitch # C15802 are approximately 1-1/8" wide so you would be able to use them, but the hooks would not quite close. For Curt clevis hooks with a larger opening there is the # C81970 which has a 1-1/3" opening, as well as the # C81980, which has an opening of 1-1/4". I've added links to video reviews of these hooks for you to take a look at as well.
