McKissick 417 Snatch Block - Wire Rope - 3/4 to 7/8 in - 12 Ton - 8 in

Description du produit

The McKissick 417 Snatch Block is a heavy-duty single-sheave block designed for wire rope cable applications requiring reliable load redirection and mechanical advantage in industrial, construction, marine, and oilfield 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 417 series accommodates wire rope cable from 3/4 to 7/8 inch in diameter.

The self-lubricating bronze bushing bearing eliminates the need for frequent greasing while providing consistent sheave rotation under load. Bronze bushing construction is well regarded for its corrosion resistance and durability in environments where exposure to moisture, dirt, and debris is common, making it a practical choice for outdoor, marine, and field applications where maintenance access may be limited. The 8-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 compact and manageable for field handling and positioning.

The snatch block configuration features a side-opening cheek plate that allows the wire rope to be inserted without threading the rope end through the block, reducing rigging time and improving setup efficiency in the field. The 417 series is a well-established McKissick product line offering dependable performance in medium to heavy wire rope rigging applications. This block is well suited for use with wire rope winches, hoists, cranes, and rigging systems in construction, marine, oilfield, logging, and general industrial lifting and pulling applications.
