McKissick 407 Super Champion Tail Board Snatch Block - 1 to 1-1/8 in - 20 Ton - 10 in - Roller Bearing

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 a 10-inch outside diameter sheave supported by a roller bearing, delivering smooth, low-friction rope travel 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 roller bearing sheave minimizes friction and heat buildup during operation, supporting reliable performance in high-cycle and sustained-load environments common to heavy field rigging.

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 compared to the Light Champion series. The 10-inch sheave diameter provides a suitable rope bend radius for the wire rope diameter range accommodated by this block while keeping the overall block profile more compact than larger sheave configurations, making it practical for applications where a high-capacity tail board block with a manageable footprint is required. 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.
