McKissick 421 Champion Snatch Block - 15 Ton - 3/4 to 7/8 in Wire Rope - 10 in Sheave - Roller Bearing

Description du produit

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 10-inch OD sheave is sized to maintain favorable rope-to-diameter ratios that help preserve wire rope condition and reduce fatigue over extended service cycles.

Equipped with a roller bearing, the 421 Champion 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 the need to thread the rope end — a practical advantage when rigging in confined spaces or when changing configurations quickly in the field. The overall block height of 629 mm reflects a compact yet structurally robust frame appropriate for the rated capacity and sheave size.

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.
