Western N-301B Series Manila Rope Steel Shell Block - 1,100 lb - 1/2 in Manila Rope - 4 in Sheave

Product Description

Product Description: The Western N-301B Series 1100 lb Manila Rope Steel Shell Block is a compact and durable single-groove rigging block 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 manageable block is required for light to medium duty rope-based lifting and pulling operations. Steel shell blocks offer the durability and strength of an all-steel construction in a compact form factor well suited to a wide range of field and shop rigging tasks. The N-301B Series is rated to an 1100 lb working load limit and is well matched to light duty rigging applications where manila rope is the preferred or specified line material.

The single 2-1/4 inch sheave accommodates manila rope up to 1/2 inch in diameter and is sized to provide reliable rope guidance within the compact overall block dimensions. The sheave runs on a self-lubricating bronze bushing bearing, a proven and low-maintenance bearing solution well suited to field rigging environments where regular lubrication may not always be practical. Self-lubricating bronze bushings deliver consistent performance across a range of operating conditions, resist corrosion, and provide reliable service life in both indoor and outdoor applications without requiring frequent maintenance intervention. The compact 4 inch block size makes the N-301B Series easy to handle and well suited to rigging configurations where space is limited or a lightweight block is preferred.

The N-301B Series steel shell block is designed for integration into general rigging, block and tackle, and rope-based lifting and pulling systems where a dependable light-capacity manila rope block in a compact steel shell configuration 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 1100 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.
