One point you are missing is that the HR bar is not rated for snatching. It is generally accepted in the 4WD world that a properly fitted HR bar (with high tensile rated bolts) is suitable for recovery - but you will never get it on paper from Hayman Reece.

The fact is that every time you introduce another link in the recovery chain you are introducing another place where something can go wrong. These adaptors (the ones I have seen) are well made, but they are welded (which can let go) and you are then also introducing a shackle (is it rated or a cheapie from China / India?).

When using this adaptor the force of the recovery is not spread over the entire length of the pin - it is focused on the holes in the HR bar and the holes in the adaptor (much like a shearing action happening on the pin).

I have never used an adaptor - I always feed the loop of the strap into the HR hole and feed the pin through it.

I have done dozens (maybe hundreds?!) of snatches in the course of the Off Road Training and Recovery courses that I have conducted and I have never seen a pin bend or break. I have however seen a couple of shackles distort to the point where they are difficult to undo.

Lastly - the adaptor is another heavy lump of metal floating around in the back of the car.

Just my two bobs worth.
