Black Sash Window Fasteners

Strong Visual Impact, Solid Performance

Finished in a durable black coating, these fasteners offer a bold aesthetic while protecting your sash windows from rattles, draughts, and misalignment. You’ll find all three key fastener types in this collection, each offering something slightly different:

• Fitch Fasteners: Compact and easy to operate, Fitch styles use a rotating cam to pull the window sashes tightly together. Their low-profile design is ideal for minimalist or contemporary interiors.
• Brighton Fasteners: With their swinging arm and twist-to-lock function, Brighton fasteners deliver strong mechanical security. Their design reflects traditional craftsmanship — ideal for ground floor or period property applications.
• Quadrant Fasteners: These use a curved lever that pivots into place, securing the sashes with a smooth swing. They add a touch of old-world charm while remaining easy to use and visually distinctive.

High Contrast, Versatile Compatibility

Whether you're finishing off dark-painted timber or creating contrast against white frames, our black sash window locks are available in locking and non-locking variations. This allows you to choose the level of functionality that suits your space — from decorative dressing rooms to secure living areas.

The matte black finish resists fingerprints and corrosion, and works especially well in design-led renovations or industrial-style interiors. These sash window fittings are easy to install and built for lasting strength.
