McKissick 434 Snatch Block - Wire Rope - 1 to 1-1/4 in - 25 Ton - 8 in - 434

Product Description

The McKissick 434 Snatch Block is a heavy-duty single-sheave block engineered for high-capacity wire rope rigging applications in oilfield, offshore, marine, heavy construction, and industrial environments. Rated for a 25-ton working load limit, this block is built around an 8-inch outside diameter sheave sized for wire rope cable from 1 to 1-1/4 inches in diameter. With overall dimensions of 9.36 inches wide by 26.56 inches high, the 434 in this configuration offers a more compact footprint than larger sheave variants in the same series while maintaining the high working load capacity required for heavy industrial rigging tasks.

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 8-inch sheave diameter provides a suitable rope bend radius for the wire rope diameter range accommodated by this block, balancing a compact overall block profile with adequate rope guidance for heavy-duty rigging operations. The overall block dimensions reflect the robust construction required to safely handle 25-ton working loads in demanding field environments.

The McKissick 434 is designed for use with heavy wire rope winches, cranes, and rigging systems where high working load capacity and dependable block construction are critical requirements. The more compact sheave and block profile of this configuration make it a practical choice for applications where a high-capacity snatch block with a smaller overall footprint is required without sacrificing the load rating needed for heavy industrial and oilfield rigging tasks.
