McKissick 431 Super Champion Snatch Block - 25 Ton - 1 to 1-1/4 in Wire Rope - 18 in Sheave

Product Description

The McKissick 431 Super Champion Snatch Block is a heavy-duty rigging block engineered for demanding lifting and pulling applications in marine, oilfield, construction, and industrial environments. Built to handle wire rope cable up to 1-1/4 inch in diameter with a 25-ton working load limit, this block delivers the strength and reliability required for critical load handling operations. The 18-inch OD sheave provides a generous rope-to-diameter ratio that helps protect wire rope integrity and extend service life under repeated heavy use.

The block features a bronze bushing bearing, which provides smooth, low-friction sheave rotation while offering excellent resistance to corrosion and wear in harsh operating conditions. The snatch block design allows the block to be opened and the wire rope inserted laterally without threading the rope end through, making rigging changes faster and more efficient in the field. At 1051 mm in overall height, the block is sized appropriately for the load capacity and sheave diameter, providing a robust frame structure suited to sustained heavy-load cycles.

The 431 Super Champion series is part of McKissick's established line of high-capacity rigging blocks, recognized across the lifting industry for consistent quality and durability. This snatch block is well suited for use with cranes, winches, and pulling systems where load redirection or mechanical advantage is required. It is recommended to verify compatibility with your specific wire rope diameter, hook or shackle attachment, and rigging system configuration before use.
