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

Description du produit

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 an 8-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 8-inch sheave diameter provides a suitable rope bend radius for the wire rope diameter range accommodated by this block while offering a more compact overall profile than larger sheave configurations, making it practical for applications where a medium-capacity tail board block with a manageable footprint is required. 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.
