Fasteners on the meeting rails help draw the upper and lower sashes together. The familiar Fitch and Brighton patterns offer different appearances and fitting requirements; neither should automatically be treated as a certified security lock.
Understanding traditional sash ironmongery
Our guidance focuses on traditional timber sliding sash and case windows, rather than assuming every modern window security fitting will work on a heritage sash.
Fitch fasteners
A common rotating meeting-rail fastener used on traditional sash windows. Confirm the shape and height of the meeting rails and the mounting footprint before ordering.
Brighton fasteners
A traditional screw-down style that draws the meeting rails together. The design and required clearances differ from a Fitch fastener.
Sash stops and restrictors
These are separate from meeting-rail fasteners. They are fitted to limit travel or provide an additional point of restraint, subject to suitability.
Choosing a finish
Polished brass, antique brass, chrome and other finishes affect appearance and maintenance. Match existing fittings where conservation of original details is important.
Repair before replacement
Original hardware can sometimes be cleaned, adjusted and refitted. Worn screw holes or distorted timber may need joinery repairs.

Frequently asked questions
Can I fit new locks to old sash windows?
Often, provided the timber is sound and the hardware suits the sash design. Check alignment, clearances and any heritage constraints first.
Will a replacement fastener make my sash window secure?
A meeting-rail fastener mainly holds the sashes together. Additional security may require appropriate locking hardware and repairs to the window itself.
