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

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 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 bronze bushing bearing, the 421 Champion delivers corrosion-resistant, low-maintenance sheave operation well suited to marine, offshore, and other moisture-exposed environments. Bronze bushings are a traditional choice in heavy rigging blocks where durability and resistance to seizing under infrequent or intermittent use are priorities. 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 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. Always confirm wire rope diameter compatibility, attachment hardware ratings, and system configuration prior to use.
