National Mfg N243-576 Single Swivel Eye Pulley 25 Lb

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N243-576 is a 0.75-inch single pulley with a swivel eye mount, built for light-duty rigging, lifting, and line-routing applications. The die-cast zinc body is copper-nickel plated for corrosion resistance, while solid brass sheaves provide smooth, low-friction operation. Rated to a safe working load of 25 pounds, this pulley is suited for indoor and outdoor environments where moisture exposure is a concern. Tradespeople and maintenance technicians reach for this fitting when a compact, no-rust pulley block is needed for cable, rope, or cord management.

This pulley is appropriate for light mechanical, maintenance, and utility rigging tasks in residential, commercial, and marine-adjacent settings. The swivel eye allows the block to rotate and align naturally with the direction of pull, reducing line wear and side loading. Typical applications include flagpole rigging, clothesline setups, small-load hoisting, and general shop or facility maintenance scenarios where a corrosion-resistant pulley is required.

Key Features

Compatibility

Designed as a general-purpose single swivel eye pulley for light-duty rigging and line-routing applications where a 0.75-inch block with a 25-pound safe working load is specified.

Installation Notes

Installation is typically performed by maintenance technicians or qualified tradespeople using standard hand tools. Ensure the mounting anchor point is rated to exceed the intended load before securing the swivel eye. Do not exceed the 25-pound safe working load under any operating condition. Inspect the swivel eye, sheave, and body for wear or corrosion before each use.
