Hey guys and gals. Yesterday, I bought 31 used bar clamps. All of them look fine but 1 of them. I have a 4' Hargrave clamp that the dog will not catch on the bar. Does anyone have any experience of how to repair this? There is a small pin on there but I am not sure how to remove it.

The bar clamps usually have a rivot on the end of them to prevent it from comming apart. You would have to drill out the rivot to get it apart but if it is slipping I doubt if it can be fixed. Probably either the bar or the clip is worn too much. Since it's made not to take apart I doubt if you can purchase parts for.

stacked locking plates?

If the clamp is similar to the Jorgenson clamps where there are 3 plates that bite into the bar when pressure is applied, these can be removed and turned over for a fresh bite. As suggested, remove the rivet, and if necessary sharpen/grind a clean edge on the metal plates.

A photo of the locking end of the clamp would be helpful. :yes:
