Superior Blocks Size 4 Single-Sheave Block With Swivel Safety Hook, Cast 2000 LB Capacity - Used

Superior Blocks (Westbrook, Maine) single-sheave cast aluminum block with a forged swivel hook and spring safety latch. Cast markings read SIZE 4 and CAP 2000 LBS, with a grease fitting on the shell and a through-bolted, bushed sheave pin. Application: general marine and shipboard rigging — davit, hauling, pot/trap hauler, and utility block service. Application not verified; sold by photographs, cast markings, and dimensions. Condition: used take-off, untested. Paint scuffs, chips, dirt, and light surface oxidation from marine service; sheave turns by hand, which is not a load test or certification. Because this is lifting equipment, it must be inspected — and where required, proof tested and certified by a qualified rigging inspector — before being placed in service. Buyer must confirm fitment by part number, photos, dimensions, engine model, serial number, and application before purchase. Used marine part sold as-is unless otherwise stated. No returns on electrical, used, special-order, or installed parts.
