McKissick 408 Light Champion Series Double Sheave Snatch Block - 4 Ton - 3/8 to 1/2 in Wire Rope - 4-1/2 in Sheave

Product Description

The McKissick 408 Light Champion Series Double Sheave Snatch Block is a wire rope rigging block engineered for versatile performance in light to medium-duty industrial, construction, and field rigging applications. Rated at 4 tons, this block features a double sheave configuration that provides greater mechanical advantage and load distribution compared to a single sheave block of equivalent size, making it well-suited for pulling, hoisting, and load-redirecting operations where efficiency and controlled line management are important. The 408 Light Champion Series is part of McKissick's established line of snatch blocks, recognized for dependable construction and broad applicability across a wide range of rigging environments.

This block features two 4-1/2 inch sheaves and accommodates wire rope cable ranging from 3/8 to 1/2 inch in diameter. The dual-groove, double sheave arrangement allows for two lines of rope to be run simultaneously or for more complex multi-part reeving configurations, increasing the mechanical advantage available to the operator and reducing the effort required to move or hold a given load. The sheaves run on bronze bushing bearings, a proven bearing type that offers reliable load-bearing capacity and resistance to shock loading in demanding field conditions where maintenance access may be limited.

The double sheave design makes this block particularly effective in block-and-tackle rigging systems, where it can be paired with a companion block to create a multi-part line arrangement for lifting or pulling loads that would otherwise exceed the practical limits of a single-sheave setup. As with all rigging hardware, proper inspection before each use, correct installation, and strict adherence to the rated working load are essential for safe operation.
