McKissick 402 Tail Board Snatch Block - 3/4 to 7/8 in - 12 Ton - 6 in - Roller Bearing

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 a 6-inch outside diameter sheave supported by a roller bearing, delivering smooth, low-friction rope travel 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 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, and offers improved sheave efficiency compared to bushing bearing configurations under repeated loading.

The compact 6-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. 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. This block is well suited for use with wire rope winches, cranes, and rigging systems in logging, oilfield, construction, and general industrial applications.
