McKissick 407 Super Champion Tail Board Snatch Block - 1 to 1-1/8 in - 20 Ton - 8 in

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 load redirection and high-tension pulling operations in industrial, oilfield, logging, and heavy construction environments. Rated for a 20-ton working load limit, this block is built around an 8-inch outside diameter sheave supported by a self-lubricating bronze bushing bearing, providing dependable, corrosion-resistant sheave rotation under sustained heavy loads. The 407 series accommodates wire rope cable from 1 to 1-1/8 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. The bronze bushing bearing offers reliable performance in environments where exposure to moisture, dirt, and debris is common, and its self-lubricating properties reduce maintenance requirements in remote or demanding field conditions.

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. The compact 8-inch sheave diameter makes this tail board configuration practical for applications where a high-capacity fixed-anchor block with a smaller overall profile is needed. This block is well suited for use with wire rope winches, cranes, and rigging systems in logging, oilfield, offshore, marine, and heavy industrial load-handling operations.
