Riggers, construction crews, and off-road enthusiasts - this is a Holland G4161 screw pin shackle, also known as a Crosby Van Beest Green Pin shackle. It's USED but fully functional - might have some cosmetic wear from previous use. Size is 1-1/2 inches (that's the pin diameter) with a 17-ton Working Load Limit (WLL). That's serious lifting capacity! The green pin indicates it's a Van Beest product, which is top quality for rigging and lifting. Screw pin shackles are super versatile - use them for towing, lifting, rigging, recovery, or any heavy-duty connection. The pin screws in and out easily. Perfect for construction sites, farms, off-road vehicle recovery, marine applications, or industrial use. Since it's used, it's more affordable than new, but still should be strong and reliable. Always inspect used rigging gear before putting it under load! But if you need a quality shackle without paying new prices, this could be just right.
