Western N-303B Series Manila Rope Steel Shell Block - 2,200 lb - 1/2 in Manila Rope - 4 in Sheave

Description du produit

Product Description: The Western N-303B Series 2200 lb Manila Rope Steel Shell Block is a compact and durable triple-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 maximum mechanical advantage and multi-part line reeving are required in a lightweight and manageable block. 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-303B Series is rated to a 2200 lb working load limit and is well matched to light to medium duty rigging applications where manila rope is the preferred or specified line material and a triple-groove configuration is required for compound block and tackle arrangements.

The three 2-1/4 inch sheave grooves allow this block to be used in multi-part line reeving arrangements with up to three rope parts running through the block simultaneously, enabling significant mechanical advantage and increased effective lifting capacity when configured in a compound block and tackle system. The sheaves run on self-lubricating bronze bushing bearings, 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-303B Series easy to handle and well suited to rigging configurations where space is limited or a lightweight triple-groove block is preferred, while the 2200 lb working load limit reflects the increased capacity enabled by the triple-groove reeving arrangement.

The N-303B Series steel shell block is designed for integration into compound block and tackle systems and rope-based lifting and pulling arrangements where a dependable light to medium capacity triple-groove 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 2200 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.
