Quick Guide to Sash Window Fasteners

Not sure which sash window fastener is right for your project? Here's a quick breakdown of the most popular types:

  • Brighton fasteners – Decorative and secure, ideal for traditional sash windows. Great draught seal but slightly bulkier.
  • Fitch fasteners – Sleek, spring-loaded and easy to use. Perfect for narrow or modern frames.
  • Hook fasteners – Simple and effective. Traditional look.
  • Quadrant fasteners – Sturdy and classic. Great for Edwardian homes, but needs precise fitting.

Frequently Asked Questions

What are sash window fasteners?

Sash window fasteners are mechanical fittings used to secure the top and bottom sashes together in a sliding sash window. They help improve security, reduce draughts, and maintain alignment.

Which type of sash window fastener is best for period properties?

Brighton fasteners and Quadrant fasteners are ideal for traditional homes. They suit Georgian, Victorian, and Edwardian sash styles with authentic designs.

Are locking sash window fasteners worth it?

Yes — locking fasteners (including key-locking options) provide extra security and are recommended for ground floor windows or properties requiring insurance-approved fittings.

Can I mix and match fasteners with other hardware?

Absolutely. Our sash fasteners are available in finishes to match sash lifts, pulleys, and architectural ironmongery for a cohesive look.
