This version of the Crosby Light Champion series ships with no hook or shackle. It's a durable block and a good starting point if you have your own means of attachment. Many of our customers look for this kind of block when they have their own shackle or hook, or an engineered application. It's made from forged steel. Available in many sizes with either bronze bushings or roller bearings. Each block is fatigue rated prior to shipment.
