I have two pins
Out and about - 250 mm pin. Shrink wrapped it myself. It goes with a 16mm, 2M length chain plus squire lock. Be careful the pin doesnt fit all 16mm & 19mm) chains. Whole thing is a tight fit with squire lock but then makes it bloody hard to attack the lock.
One in the photo is a 300mm as chain goes through anchor with both ends on the pin.
