Cable Block

304 Stainless Steel Cable Block

The Cable Block is a compact, light-duty pulley built for routing and redirecting small-diameter wire rope rather than heavy hoisting or rigging. At 3/8" wire rope capacity with a 1" sheave, it's sized for cable runs on trailers, marine equipment, and fixed installations where you need to change cable direction without the bulk of a full snatch block. The 304 stainless steel body resists corrosion in outdoor and marine environments, and the brass-bushed sheave keeps cable moving smoothly as it passes through.

Common Uses

• Light-duty cable routing on trailers and equipment
• Marine cable and wire rope redirection
• Fixed installations needing a small, corrosion-resistant pulley point
• Applications where a full-size snatch block is more capacity than the job needs

Specifications

This is a light-duty cable pulley, not a rigging or hoisting block - it's not rated or intended for lifting or load-bearing rigging applications. If your job needs a working load limit for pulling, winching, or lifting wire rope, size up to a snatch block instead. Contact our Product Experts if you need documentation beyond what's listed here for your specific application.

Complete the Job

If this cable block is undersized for your application, step up to a snatch block rated for wire rope pulling and winching - browse the Snatch Block w/ Hook SS 304, 4190 Snatch Block w/ Shackle, or 4180 Snatch Block w/ Hook collections, or check Crosby® McKissick® Snatch Blocks for heavier-duty rigging needs.

Frequently Asked Questions

Is this the same as a snatch block?
No. A cable block is a smaller, fixed pulley for routing and redirecting light-duty cable. A snatch block is built for rigging and typically opens on one side to load wire rope under working loads. If your application involves pulling, winching, or lifting, use a snatch block rather than a cable block.

Why 304 stainless steel and a brass bushing?
304 stainless resists corrosion in wet, salt-exposed, and outdoor conditions, which matters for marine and trailer use. The brass bushing supports the sheave as it rotates, keeping cable movement smooth and reducing wear.

What's the maximum load this block can handle?
This is a light-duty cable routing pulley rather than a load-rated rigging block. If your application requires a documented working load limit, choose a rigging-rated snatch block instead, or contact our Product Experts for guidance on the right product for your load requirements.

What size wire rope does it fit?
This cable block is sized for 3/8" wire rope with a 1" sheave.
