Every order helps keep your local hardware store on the corner.

Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

About Product Overview

Koch Industries 1 in. Nickel Aluminum Ridge Eye Single Sheave Rigid Eye Pulley is a compact, high-performance solution built for reliable rope control in tight spaces. The combination of a durable aluminum body and a nickel finish offers lightweight strength with enduring corrosion resistance, making it suitable for shop, boat, or field use where dependable performance matters.

The Ridge Eye design paired with a rigid eye configuration ensures precise alignment and secure mounting. This means your rope sits cleanly in the groove, minimizes side-to-side movement, and reduces wear over time. The single sheave arrangement provides smooth, controlled rope flow with predictable performance under load.

Technical highlights include a 1-inch wheel diameter and a maximum rope diameter of 5/16 inch, allowing for straightforward, safe operation on standard lines without overloading the pulley. With a working load rating of 30 (units as specified), this pulley is engineered for light-to-moderate hauling, tensioning, and guiding tasks where space or weight constraints matter.

Who should consider this pulley? Ideal for DIY enthusiasts, marine or small-boat riggers, installers, and maintenance professionals tackling precise line management in constrained environments. Its combination of light weight, sturdy aluminum construction, and corrosion-resistant nickel finish makes it a practical upgrade over bulkier, less-specific pulleys for everyday line control and rigging jobs.

Practical applications and use cases:

  • Guiding and redirecting lines on compact hoists, shop cranes, or portable rigs.
  • Small-boat rigging and deck setups where space is at a premium.
  • Light tensioning tasks in outdoor installations or temporary setups.

Key considerations for optimal performance:

  • Ensure the rope diameter stays at or below 5/16 inch to maintain smooth operation and reduce wear.
  • Securely mount the rigid eye to a solid anchor point to minimize movement under load.
  • Regularly inspect the groove for wear and the eye for any deformation after use.

Their Counter
Try local first · we'll wait

The stores we send you to are local and independently run — often for generations, the kind of place where someone behind the counter knows the regulars. We don't own them. We just think they deserve the foot traffic. They can put most of what we sell on their next truck. Ask there before you check out here.

About our directory. National Hardware Group is an independent retailer and directory. The local stores we list and link to are separately owned and operated — we have no ownership stake in any of them, and most pay us nothing to be included. That includes plenty of stores flying a co-op banner that people don't realize are locally owned and run, not operated by a corporation. Store owners can choose to upgrade their listing for an enhanced presence or pickup features, but the base directory is free, and inclusion is never a paid endorsement.
