Enerpac 0F6C Model RWR-100 single action swing clamp. Threaded body appears to be 1-7/8 - 16. I am unsure if clamps work, but do move freely and appear to be in decent condition. They have been sitting in storage for many years and were never used by us. Buyer will receive two clamps as pictured. If there are any additional questions, please ask. Returns are accepted, however buyer pays return shipping. SI 162
