McKissick 431 Super Champion Snatch Block - 1-1/8 in - 20 Ton - 14 in - Bronze Bushing

Description du produit

The McKissick Series 431 Super Champion Snatch Block is a heavy-duty single-sheave block engineered for high-capacity rigging, pulling, and load-redirection operations across the most demanding industrial applications. Rated to a 20-ton working load capacity and designed to accommodate wire rope up to 1-1/8 inch in diameter, the Series 431 delivers the structural integrity and sustained performance required in oilfield, construction, marine, and offshore environments. The 14-inch sheave outside diameter provides a generous rope bend radius, helping to reduce wire rope fatigue and extend rope service life under repeated heavy-load cycles.

This Super Champion variant is fitted with a bronze bushing bearing, a bearing type proven in heavy industrial block applications for its high load-bearing capacity, durability, and resistance to contamination and harsh field conditions. 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 along its length without threading the line — a critical operational advantage in field rigging setups where time and accessibility are factors.

McKissick's Super Champion designation identifies a reinforced, high-capacity tier within their block product line, built for sustained use under demanding working loads where standard blocks would be inadequate. The Series 431 is commonly used with heavy winches, cranes, and pulling systems to redirect wire rope leads or to develop mechanical advantage in large tackle assemblies. All shackles, hooks, and attachment hardware used in conjunction with this block should be rated to match or exceed the 20-ton working load limit to maintain a safe and compliant rigging assembly.
