CURT safety pins can also be purchased with a 12" chain attachment to mount onto your trailer coupler and prevent the safety pin from being misplaced.

## Questions & Answers

**Q: Are these really 5/16" diameter?  I just bought the 1/4" pins but they were only 3/16" diameter.**
A: yes.

**Q: whats the shear rating?**
A: The shear strength is virtually irrelevant. There is next to no force against it by the lever. It just keeps the lever from popping up. A good twig or wood dowel could do the same thing.

**Q: What is the shear rating? I would be using this in pla e of a bolt un a weight lifting bench.  The rack is supposed to hold 600 pounds.**
A: This pin is only used to "lock" the clamping mechanism and as such has no relative shear rating.

**Q: what is the dimension from the shaft  to the wire (looking for clearance of 1-3/4" )?**
A: From the Amazon Product Dimensions: 7 x 2 x 2 inches.  The 5/16" shaft would make the gap less less than the 1-3/4" you need, but you could bend the wire part as needed.  It's really flexible and easy to bend.
