McKissick 421 Champion Snatch Block - 15 Ton - 3/4 to 7/8 in Wire Rope - 8 in Sheave - Roller Bearing

Product Description

The McKissick 421 Champion Snatch Block is a rugged, high-capacity rigging block designed for wire rope applications in crane, winch, marine, oilfield, and heavy construction operations. Rated for a 15-ton working load limit and compatible with wire rope cable from 3/4 inch up to 7/8 inch in diameter, this block provides reliable load redirection and mechanical advantage in demanding field environments. The 8-inch OD sheave offers a more compact profile than larger-sheave variants in the 421 Champion line while maintaining the structural integrity required for the rated load capacity.

Equipped with a roller bearing, this block delivers smooth, efficient sheave rotation under load, reducing friction and heat generation during sustained pulling or lifting operations. The snatch block configuration allows the block to be opened at the side plate, enabling the wire rope to be inserted laterally without threading the rope end — a practical advantage when rigging in confined spaces or when changing configurations quickly in the field. The overall block height of 584 mm reflects a compact yet structurally sound frame well suited to applications where a smaller footprint is beneficial without sacrificing rated capacity.

The 421 Champion series is part of McKissick's well-established line of industrial rigging blocks, built to perform consistently in harsh and high-cycle environments. This block is suited for use wherever load redirection, fleet angle management, or added mechanical advantage is required in a wire rope rigging system. Always confirm wire rope diameter compatibility, attachment hardware ratings, and system configuration prior to use.
