All blocks 356mm and larger are furnished with McKissick® Roll Forged™ sheaves with flame hardened grooves. Recessed sideplate design reduces the gap between the sheave rim and the sideplate, allowing the sheave assembly to be captured in the block if loss of center pin occurs. Sealed tapered roller bearings extend the life of the center pin and bearings, and allows for faster line speeds than recommended with standard snatch blocks. Shackle fitting swivels for easy positioning.
