McKissick Snatch Block - 3/4 to 7/8 in - 12 Ton - 6 in

Product Description

The McKissick Series 417 Snatch Block is a heavy-duty single-sheave block engineered for demanding rigging, pulling, and lifting applications across construction, oilfield, marine, and industrial environments. Rated to a 12-ton working load capacity and compatible with wire rope diameters from 3/4 to 7/8 inch, the Series 417 is designed to redirect wire rope loads efficiently while maintaining structural integrity under sustained working loads. The 6-inch sheave outside diameter offers a compact profile suited to applications where space or weight constraints are a consideration, while still delivering the load-handling capability required for 12-ton rigging operations.

This variant of the Series 417 is fitted with a bronze bushing bearing, a bearing type valued in heavy industrial block applications for its durability, high load-bearing capacity, and resistance to contamination and harsh environmental conditions encountered in field use. The snatch block design incorporates a side-opening cheek plate, allowing the block to be attached to or removed from a wire rope at any point without threading the line — a critical advantage in field rigging setups where time and accessibility are factors.

McKissick is a long-established brand in the block and sheave industry, and the 417 series reflects their commitment to precision manufacturing and load-rated performance. These blocks are commonly used in conjunction with winches, cranes, and pulling equipment to change the direction of a wire rope lead or to increase mechanical advantage in a tackle system. Proper selection of shackles, hooks, and attachment hardware rated to the block's working load limit is essential for safe rigging practice.
