Product description
1 ¾″ Sash Pulley – Polished Black
1 3/4 sash pulley polished black combines a bold architectural finish with smooth cord guidance for timber sash windows. It supports the counterweight system so the sash lifts and lowers with consistent control.
Why choose 1 3/4 sash pulley polished black
Firstly, the 1¾″ format suits many standard sash frames, so it works well for replacements. Secondly, the pulley improves cord alignment, which helps reduce rubbing and extends cord life. Additionally, the polished black finish pairs well with modern hardware, yet it still looks at home in period renovations.
Performance benefits
- Smoother cord travel to support easy window operation
- Reliable guidance that helps reduce wear on cords
- Ideal for refurbishment, restoration, and joinery projects
- Distinct Polished Black finish for coordinated ironmongery
Complete the system
For best results, combine pulleys with correctly matched sash weights and a quality cord. That way the sash balances properly and remains stable during daily use.

History of Sash Pulleys
Sash pulleys developed in Britain during the late 17th century alongside the rise of sliding sash windows. Early sash windows used a counterweight system hidden inside the timber box frame. However, builders needed a reliable way to guide the cord smoothly over the frame head. As a result, craftsmen introduced small rotating pulley wheels mounted in metal housings to reduce friction and improve lifting control.
Georgian Period Development
During the Georgian era, sash windows became a defining architectural feature in townhouses and public buildings. Joiners began standardising pulley sizes to suit common sash box dimensions. Brass quickly became a preferred material because it resisted corrosion, rotated smoothly, and matched other traditional window fittings. Consequently, brass sash pulleys became a staple component in quality window construction.
Victorian Advancements
In the Victorian period, glass panels became larger and heavier. Therefore, sash windows required stronger counterweight systems and more durable pulleys. Foundries improved casting techniques, which helped manufacturers produce stronger housings and smoother-running wheels. These changes increased lifespan, reduced cord wear, and supported wider use of sash windows across expanding urban housing.
20th Century to Modern Use
Throughout the 20th century, sash pulleys kept the same basic mechanical principle. Even so, manufacturers refined machining processes to improve rotation efficiency and consistency. In addition, modern finishing methods and protective coatings improved durability while preserving the traditional look.
Today, sash pulleys still follow the same engineering concept developed over 300 years ago. Restoration specialists and joinery professionals continue to use brass and precision-machined pulley systems to maintain authentic performance in heritage properties, while benefiting from improved manufacturing accuracy and long-lasting materials.
