Specifications

What it's used for

• Securing the meeting rails of traditional vertical sliding sash windows in period and heritage properties.
• Replacing worn or broken fasteners on existing timber sash windows without altering the frame or sash.
• New-build timber sash window joinery where a period-appropriate, rotating-cam fastener is specified.
• Conservation and restoration projects where matching brass or chrome ironmongery is required to complement existing hardware.

Fitting and handling

The Fitch fastener mounts to the top rail of the inner sash and the meeting rail of the outer sash using the supplied or standard countersunk screws. The swivelling cam features a rising gradient lip, which draws the two meeting rails together more firmly the further the handle is rotated, so accurate alignment of the two halves before fixing is important for a positive engagement. Store the fastener in dry conditions prior to fitting, and avoid contact with solvent-based wood finishes that could dull the polished surface.

FAQ

What is a Fitch pattern sash fastener and how does it differ from other sash fasteners?

A Fitch pattern fastener uses a rotating cam with a rising gradient lip that locks the two meeting rails of a sash window together. Unlike a straight bullet or Brighton fastener, the cam draws the rails progressively tighter as it is turned, giving a firmer and more secure closure without the need for a separate locking bolt.

Will this fastener fit my existing sash window?

The Fitch pattern is a widely used standard design, so in most cases it will align with existing screw holes on traditional timber sash windows. It is worth checking the position of the existing body and keep plate before ordering, as meeting rail depths can vary between older and modern frames.

Is polished brass or polished chrome better for a period timber sash window?

Both finishes are appropriate for traditional sash windows. Polished brass is the more historically accurate choice for Victorian and Edwardian properties, while polished chrome suits later twentieth-century properties or where a cooler, more contemporary look is preferred alongside existing chrome furniture. Both variants are priced identically at £13.68.
