Break Testing the Break Tester
We use these bomber 2 ton chain shackles in our break test machine. After bending one while testing a forged steel ring, we decided to find out how strong they really are. It broke at 75 kN. At only $4.30, that's 3x the strength of a steel carabiner at 1/6th of the price.
