Period-Style Quadrant Fasteners Built for Timber Sash Windows
Classic Design, Lasting Performance
Quadrant fasteners are an essential finishing touch for anyone restoring or maintaining traditional sash windows. These fasteners feature a curved arm that rotates into a catch to tightly secure the window’s top and bottom sashes, preventing movement and reducing draughts.
Often found in Georgian and Victorian properties, the sash window quadrant catch is valued for both its aesthetics and function. They're especially suited to older timber frames or conservation properties where maintaining heritage appearance is key.
Choose from a wide range of finishes including:
- Polished Brass – perfect for Georgian-style homes
- Antique Brass and Beeswax – ideal for rustic or farmhouse properties
- Polished Chrome or Satin Nickel – suited to more refined or updated interiors
- Matt Black and Pewter – modern alternatives with a vintage feel
