This snatch block is what many other models are based on--it's pretty much the industry standard. Though considered the "418 Light Champion" by Crosby, there's nothing light-duty about the design or performance. It's made from forged steel with an alloy, heat-treated hook (latch kits are optional). Available in a variety of sizes with either bronze bushings or roller bearings, and easily reeved. Each block is fatigue rated prior to shipment.
