Western S-412B Series Synthetic Fiber Rope Steel Block - 3,000 lb - 1/2 in Synthetic Fiber Rope

Product Description

Product Description: The Western S-412B Series 3000 lb Synthetic Fiber Rope Steel Block is a compact and durable double-groove rigging block designed for use with synthetic fiber rope cable up to 1/2 inch in diameter in general rigging, construction, marine, and industrial applications where multi-part line reeving and increased mechanical advantage are required in a lightweight and manageable block. Standard steel 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 S-412B Series is rated to a 3000 lb working load limit and is well matched to light to medium duty rigging applications where synthetic fiber rope is the preferred or specified line material and a double-groove configuration is required for block and tackle arrangements with 1/2 inch rope.

The two 2-1/4 inch sheave grooves allow this block to be used in multi-part line reeving arrangements, enabling greater mechanical advantage and increased effective lifting capacity when configured in a 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 accommodates the 1/2 inch rope diameter and two 2-1/4 inch sheaves in a lightweight and manageable steel block form factor suited to a wide range of rigging configurations, and the 3000 lb working load limit reflects the increased capacity enabled by the double-groove reeving arrangement.

The S-412B Series standard steel block is designed for integration into block and tackle systems and rope-based lifting and pulling arrangements where a dependable light to medium capacity double-groove synthetic fiber rope block in a compact steel 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 3000 lb or greater, and the block must be inspected before each use in accordance with applicable lifting and rigging safety standards. Synthetic fiber rope must be inspected for wear, abrasion, and degradation before each use and replaced when signs of deterioration are present.
