McKissick 407 Super Champion Tail Board Snatch Block - 1-1/4 in - 30 Ton - 24 in - Bronze Bushing

Product Description

The McKissick 407 Super Champion Tail Board Snatch Block is a heavy-duty single-sheave block with tail board configuration, designed for wire rope cable applications requiring a securely mounted, fixed-anchor block for high-capacity load redirection and pulling operations in oilfield, offshore, logging, and heavy construction environments. Rated for a 30-ton working load limit, this block is built around a 24-inch outside diameter sheave supported by a self-lubricating bronze bushing bearing, providing reliable, corrosion-resistant sheave rotation under sustained heavy loads. The 407 series accommodates wire rope cable up to 1-1/4 inches in diameter.

The tail board attachment provides a flat, bolted mounting interface that allows the block to be securely fastened to a vehicle frame, sled, skid, or structural anchor, keeping the block fixed in position during high-tension pulling and rigging operations. This configuration is commonly used in logging, land clearing, oilfield, and heavy construction applications where a stationary anchor block is required to redirect a winch or crane line efficiently under high load. The bronze bushing bearing offers reliable performance in environments where exposure to moisture, dirt, and debris is common, and its self-lubricating properties reduce the frequency of maintenance required to keep the block operating reliably in remote or demanding field conditions where routine servicing is not practical.

The 24-inch sheave diameter provides an exceptionally generous rope bend radius that minimizes wire rope fatigue and extends rope service life across repeated heavy loading cycles, a critical advantage in high-capacity tail board applications where large-diameter wire rope is subjected to sustained tension and repeated bending. The Super Champion designation reflects McKissick's higher-strength design tier, engineered for demanding applications where greater working load limits and more robust construction are required. This block is well suited for use with heavy wire rope winches, cranes, and rigging systems in logging, oilfield, offshore, marine, and heavy industrial load-handling operations.
