Description du produit

Product Description: The Western S-21B Series 1000 lb Manila Rope Wood Block is a compact and traditional single-groove rigging block featuring a classic wood shell construction designed for use with manila rope cable up to 1/2 inch in diameter in general rigging, construction, marine, and industrial applications where a lightweight and easily managed block is required for light duty rope-based lifting and pulling operations. Regular wood blocks offer the time-tested durability and rope-friendly characteristics of a wood shell construction in a compact form factor well suited to a wide range of field, marine, and shop rigging tasks. The S-21B Series is rated to a 1000 lb working load limit and is well matched to light duty rigging applications where manila rope is the preferred or specified line material and a single-groove wood block for 1/2 inch rope is required.

The single 2-1/4 inch sheave accommodates manila rope up to 1/2 inch in diameter and provides reliable rope guidance within the compact overall block dimensions. The sheave runs on a bronze bushing bearing, providing reliable and consistent performance in field and shop rigging environments across a range of operating conditions. The compact 4 inch block size makes the S-21B Series easy to handle and well suited to rigging configurations where space is limited or a lightweight single-groove wood block is preferred for light duty 1/2 inch manila rope applications. The wood shell construction is particularly well suited to marine and traditional rigging environments where the rope-friendly surface of the wood shell helps minimize rope wear at the shell contact points.

The S-21B Series regular wood block is designed for integration into general rigging, block and tackle, and rope-based lifting and pulling systems where a dependable light-capacity single-groove manila rope block in a traditional wood shell construction is required. The block is compatible with standard rigging hardware including hooks and shackles rated to the appropriate working load limit. All connected rigging components must be rated to 1000 lb or greater, and the block must be inspected before each use in accordance with applicable lifting and rigging safety standards. Manila rope must be inspected for wear, fraying, and degradation before each use and replaced when signs of deterioration are present.
