McKissick 443 Lay Down Block - 0.5 Ton - 3/4 in Wire Rope - 6 in Sheave

Product Description

The McKissick 443 Lay Down Block is a purpose-built rigging block designed for lay down and horizontal rope handling applications where a low-profile block orientation is required to guide wire rope along a surface or through a system without the vertical suspension typical of standard hoisting blocks. Rated for a 1/2-ton working load limit and compatible with wire rope cable up to 3/4 inch in diameter, this block is suited for use in oilfield, marine, construction, and general industrial operations where controlled rope lay down, pay-out, or horizontal rope management is needed.

The block features an anti-friction bearing, which provides smooth, efficient sheave rotation under load while reducing friction and wear during rope movement. The steel sheave offers a durable, wear-resistant rope contact surface appropriate for wire rope applications in field environments. The 6-inch OD sheave is sized to provide a suitable bend radius for 3/4-inch wire rope, helping to preserve rope integrity during repeated lay down and retrieval cycles. The regular configuration of the 443 series represents the standard lay down block design within this product line.

The McKissick 443 series lay down block is a recognized product in oilfield and industrial rigging inventories, commonly used in applications such as wireline operations, rope management on deck or ground level, and other horizontal or low-angle rope handling tasks. The block's construction is intended to withstand the abrasion and impact exposure common in lay down service environments. Always confirm wire rope diameter compatibility, load ratings, and system configuration before placing the block into service.
