McKissick Lead Block - 1 in - 26 in - 33 in L X - 33 in W

Product Description

The McKissick Series 463 Lead Block is a heavy-duty horizontal configuration block engineered for large-scale wire rope lead management in demanding oilfield, drilling, and industrial pulling applications. Designed to accommodate wire rope up to 1 inch in diameter and featuring a 26-inch sheave outside diameter, the Series 463 provides the generous rope bend radius required to protect wire rope integrity under sustained high-load and high-cycle operating conditions. The horizontal orientation of this lead block is specifically suited to applications where the wire rope must be redirected along a horizontal plane, such as from a drawworks or winch drum to a crown block or traveling block system.

With overall dimensions of 33 inches in length by 33 inches in width, the Series 463 is a substantial piece of rigging equipment built to handle the structural demands of heavy drilling and pulling operations. The large sheave diameter and robust housing construction are characteristic of McKissick's lead block designs, which are intended for fixed installation points where the wire rope enters or exits a block-and-tackle system at a controlled angle. Proper fleet angle management is critical in lead block applications to minimize rope wear and ensure even spooling on the drum.

McKissick has a long-established reputation in the oilfield and industrial block industry for precision manufacturing and load-rated performance. The Series 463 lead block is designed for integration into larger rigging and hoisting systems where consistent wire rope alignment and load transfer are essential to safe and efficient operation. All mounting hardware, attachment points, and associated rigging components should be selected and rated to match the demands of the intended application.
