ABSTRACT:
This shackle consists primarily of a pair of "U"-shaped members, a leg of each threading into each other, so as to form a pivotal joint, which enables the shackle to be easily applied to a chain, even under adverse conditions. The shackle further includes a tapered clincher head pin, and the opening in a mating clincher head is tapered at the bottom and countersunk at the top, so as to allow swedging of the pin therein.
