McKissick 407 Super Champion Tail Board Snatch Block - 25 Ton - 1 to 1-1/4 in Wire Rope - 18 in Sheave

Description du produit

The McKissick 407 Super Champion Tail Board Snatch Block is a heavy-duty rigging block engineered for high-capacity wire rope applications where a tail board attachment provides a fixed anchoring or directional control point within the rigging system. Rated for a 25-ton working load limit and compatible with wire rope cable from 1 inch up to 1-1/4 inches in diameter, this block is built for demanding crane, winch, marine, oilfield, offshore, and heavy construction operations where the tail board configuration offers a structural mounting advantage not available with hook or shackle suspension styles.

The 18-inch OD sheave provides a generous rope-to-diameter ratio appropriate for 1 to 1-1/4-inch wire rope, supporting favorable bend characteristics that help reduce rope fatigue and extend service life under repeated heavy loading cycles. Equipped with a bronze bushing bearing, the block delivers corrosion-resistant, low-maintenance sheave rotation well suited to marine, offshore, and other harsh or moisture-exposed environments. Bronze bushings offer inherent resistance to seizing and corrosion, making them a dependable choice for high-capacity rigging blocks used in demanding or infrequently serviced field conditions.

At 18.25 inches wide and 24.62 inches in overall height, the 407 Super Champion presents a large, robust frame construction appropriate for the rated capacity and sheave diameter, reflecting the structural demands of 25-ton tail board snatch block service. The snatch block design allows the side plates to be opened for lateral rope insertion, enabling efficient rigging changes without threading the rope end through the block — a practical advantage during field reconfiguration or when working in confined spaces. The 407 Super Champion series is part of McKissick's high-capacity rigging block line, recognized across marine, oilfield, and heavy industrial markets for consistent quality and durability. Always confirm wire rope diameter compatibility, tail board attachment point ratings, and full system configuration before placing the block into service.
