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

Description du produit

The McKissick 402 Tail Board Snatch Block is a medium-capacity snatch block engineered for rigging and load redirection applications requiring a 12 Ton working load capacity. Designed to accommodate wire rope from 3/4 to 7/8 inch in diameter, this block features a 10-inch outside diameter sheave that provides a suitable rope bend radius for the wire rope sizes commonly used in construction, oilfield, logging, and general industrial rigging operations. The tail board configuration provides a flat mounting plate or tail attachment point that allows the block to be secured directly to a structure, beam, or deck fitting, making it well suited for applications where a fixed, stable block mounting is required rather than a hook or shackle suspension.

The 402 is fitted with roller bearings that provide reliable performance under the radial and axial loads generated during load line redirection. Roller bearings offer improved load capacity and reduced friction compared to plain bushing designs, supporting smooth sheave rotation under the working loads associated with 12 Ton rigging operations. This bearing type is well established in medium-duty industrial snatch block applications and supports dependable performance across the variable load conditions encountered in construction, oilfield service, logging, and marine deck rigging environments.

As a snatch block, the McKissick 402 Tail Board incorporates an openable side plate that allows wire rope to be inserted laterally without threading the rope end through the block, enabling efficient rigging changes and load line redirection in the field. The tail board mounting configuration makes this block particularly useful in logging operations, construction site rigging, and marine deck applications where the block must be secured to a fixed structure and repositioned as needed during operations. Always verify working load limits, wire rope diameter compatibility, and mounting hardware compatibility prior to placing the block into service.
