McKissick 402 Tail Board Snatch Block - 3/4 to 7/8 in - 12 Ton - 10 in

Product Description

The McKissick 402 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 pulling operations in industrial, construction, oilfield, and logging environments. Rated for a 12-ton working load limit, this block is built around a 10-inch outside diameter sheave supported by a self-lubricating bronze bushing bearing, providing dependable, corrosion-resistant sheave rotation under sustained loads. The 402 series accommodates wire rope cable from 3/4 to 7/8 inch 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 the frequency of maintenance required to keep the block operating reliably in remote or demanding field conditions.

The 10-inch sheave diameter provides a more generous rope bend radius than smaller sheave configurations in the same series, reducing wire rope fatigue and extending rope service life across repeated loading cycles while keeping the overall block profile practical for field handling and positioning. The 402 series is a well-established McKissick product line known for dependable performance across a wide range of medium to heavy load-handling tasks in field environments, and this configuration offers a balance of improved rope bend radius and manageable block size within the tail board snatch block product family.
