McKissick Snatch Block - 3/4 to 7/8 in - 12 Ton - 10 in - Roller Bearing

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. Built to handle maximum cable diameters from 3/4 to 7/8 inch, this block is designed to redirect wire rope loads efficiently while maintaining structural integrity under sustained working loads up to 12 tons. The robust housing and precision-engineered components make it a reliable choice for operations where performance and safety margins are non-negotiable.

The Series 417 features a 10-inch sheave outside diameter paired with a roller bearing assembly, which significantly reduces friction during operation and extends both sheave and wire rope service life compared to plain bearing alternatives. 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.
