Western Hoist S-21B Series Wood Block - 2,800 lb - 7/8 to 1 in Manila Rope

Description du produit

Product Description: The Western Hoist S-21B Series Wood Block is a single-groove rigging block designed for manila rope and cable applications ranging from 7/8 inch to 1 inch in diameter. Built around a 4-3/4 inch outside diameter sheave with a bronze bushing bearing, this larger-format block provides smooth, dependable rope travel for lifting, pulling, and load-redirection tasks across marine, logging, agricultural, and general industrial applications where heavier rope sizes are required.

Constructed with a hardwood shell, the S-21B in this configuration offers a working load capacity of 2,800 lb and an 8-inch block length. The single-groove sheave is sized to accommodate manila rope and compatible cable from 7/8 inch up to 1 inch in diameter, ensuring proper rope seating and reducing wear during sustained use. The bronze bushing bearing delivers consistent performance under load with minimal maintenance requirements.

The S-21B is part of Western Hoist's line of wood shell blocks, well suited for use in tackle systems where traditional rigging hardware is preferred. The larger 8-inch shell and 4-3/4 inch sheave make this configuration appropriate for heavier rope sizes and higher-load single-part line applications. These blocks are commonly employed in block-and-fall arrangements to redirect or support loads in medium-to-heavy rigging operations across field and shop environments.
