McKissick Lead Block - 1-1/2 in - 26 in V - 461

Product Description

The McKissick Series 461 Lead Block is a heavy-duty vertical configuration block engineered for wire rope lead management in oilfield, drilling, and heavy industrial pulling applications. Designed to accommodate wire rope up to 1-1/2 inch in diameter and featuring a 26-inch sheave outside diameter, the Series 461 in this configuration is built for high-capacity applications where large rope diameters and substantial structural loads are the norm. The vertical orientation is specifically suited to applications where the wire rope must be redirected along a vertical plane, such as in derrick, mast, or fixed overhead rigging installations where controlled rope alignment into a hoisting system is required.

With overall dimensions of 16 inches in length by 38 inches in width, this configuration of the Series 461 reflects the increased size and mass required to handle 1-1/2 inch wire rope under demanding operating conditions. The large 26-inch sheave outside diameter provides a generous rope bend radius, helping to reduce wire rope fatigue and extend rope service life during high-cycle, heavy-load operations. The robust housing construction is characteristic of McKissick's lead block designs, intended for fixed installation points where the wire rope enters or exits a block-and-tackle system at a controlled angle, with proper fleet angle management essential to minimize rope wear and side loading on the sheave.

McKissick has a long-established reputation in the oilfield and industrial block industry for precision manufacturing and load-rated performance. The Series 461 vertical 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 and rope diameter.
