All of the snatch blocks that I have listed. The Pullys and or swivels move freely. They may need new Grease Zerks. An electric supply / welding shop owner passed and I attended the estate liquidation.
I acquired many items at this sale. This one says has a crosby g3e LG hook and a johnson swivel Block 12jh It's very large and measurements are shown in photos. It's used and has lots of paint wear.
