Description
Product Overview
The WRS Universal Constant Force Coil Spring is engineered for durability and performance in demanding window balance applications. Constructed from high‑grade stainless steel, the coil resists corrosion, rust, and wear, making it suitable for both residential and commercial environments where longevity is essential. Its single hook‑in style simplifies installation, allowing technicians to attach the spring quickly without the need for additional hardware. Measuring a precise 31/64″ (0.481″) width, the spring integrates seamlessly with standard carriers, pivot lock shoes, and coil‑style balance systems found in vinyl, aluminum, and wood tilt windows. The spring’s force range, from 1 to 5 lb (model #3.5) up to 18 lb (model #10), provides flexibility to match a variety of window sizes and weight requirements, ensuring consistent operation over the life of the window. The product dimensions of 35 × 0.41 × 0.08 in and a lightweight of 1.76 oz make handling and storage straightforward, while the American‑style design reflects a commitment to quality and compatibility with North American window hardware standards.

Usage
Designed for a broad spectrum of window balance systems, this coil spring excels in both new installations and retrofit repairs. Homeowners renovating older properties will find the spring an ideal replacement for worn or broken balances, restoring smooth operation to windows that have become difficult to open or close. Property managers overseeing multi‑unit buildings can rely on the spring’s consistent force output to maintain uniform performance across dozens of windows, reducing tenant complaints and maintenance calls. Contractors working on commercial projects benefit from the spring’s robust construction, which tolerates frequent use and exposure to varying temperature conditions without loss of tension. The hook‑in design eliminates the need for specialized tools, allowing installers to secure the spring in seconds, which translates to lower labor costs and faster project turnaround. Whether the application involves a single residential window or a large portfolio of commercial glazing, the spring’s versatility and ease of use make it a go‑to solution for professionals seeking reliable, repeatable results.

FAQ
What window types are compatible with this spring?
The coil spring is compatible with most standard tilt‑window systems, including vinyl, aluminum, and wood frames that use carrier, pivot lock shoe, or coil‑style balance mechanisms. Its 31/64″ width ensures a proper fit for the majority of commercially available balance carriers.
How do I determine the correct force rating for my window?
Identify the weight of the sash and the size of the window opening. WRS provides a sizing chart that correlates window dimensions with the appropriate spring force range. Selecting a spring within the recommended range guarantees smooth operation without over‑ or under‑loading the balance system.
Can the spring be reused after removal?
Yes, the stainless‑steel coil can be reused if it remains undamaged and retains its original shape. However, for optimal performance and to avoid potential fatigue, many professionals recommend installing a new spring during a balance repair to ensure consistent tension.
What warranty does WRS offer on this product?
WRS provides a limited one‑year warranty covering manufacturing defects. If the spring fails due to a defect within this period, we will replace it at no cost, reinforcing our confidence in the product’s durability.
Is special tooling required for installation?
No special tools are needed. The single hook‑in design allows the spring to be attached directly to the carrier or lock shoe by hand, making the installation process quick and straightforward for both DIY enthusiasts and professional installers.
