I did not write the number down and it is hard to measure on the split clamp. Both of my Krags are assembled and I do not want to break them down to measure.
Thought of it later, do you want to borrow this one and the barrel clamp? Pay the shipping both ways and pad the clamps with paste board while you are using them so they do not get scarred up. We can send it today if you want. Send me a private message with your email address and we can work out the details if you want to do this.
