From left to right — the evolution of the locking removable bolt plate (LRBP). Hope to be pull testing prototype 3 (right) soon and get above the 12kN that V2 (middle) got.

Pull to destruction got to be more fun for V2 on a 30kN machine. Will also be doing drop tests on V3 with a load cell to get some graphs on how it performs in a severe climbing fall.
