Sash Window Hardware

Learn more about sash window hardware

Sash window hardware must balance traditional styling with modern mechanical strength. Traditional vertical sliding timber sashes rely on balanced counterweights, smooth-running pulleys, and firmly locked meeting rails to keep draughts, water ingress, and unwanted noise out. Fitting high-grade components ensures smooth operation over decades of seasonal timber movement while preserving the integrity of listed, conservation, and period properties. 

Typical uses

• Replacing worn sash window locks, catches, lifts and fasteners that no longer hold or operate cleanly.

• Renewing the moving hardware that keeps a sash balanced and running, including pulleys, cords, weights and springs.

• Adding safety fittings such as sash window restrictors where the property and use call for them.

How to choose the right sash window hardware

• Match the hardware to the existing style, fixing method and frame material so the replacement works without reworking the sash.

• Get the key dimensions right before you commit. For locks and fasteners, check spindle size, backset, mortice depth and hole spacing against the old fitting.

• Know what each fitting does. Sash window locks secure the sashes together. Catches and fasteners hold them closed and pull them tight. Lifts give you a fixing to raise the lower sash.

• For the moving hardware, compare your options carefully. Traditional box sashes run on pulleys, sash cord for windows and sash window weights, so cord diameter and weight need to balance the sash.

• Spring balanced sashes use sash window springs instead, and the two systems are not interchangeable, so confirm which one yours uses before ordering.

• Where a window is within reach of children, consider restrictors and finger safe options, and check what is appropriate for the property and any local requirements.

Before you order

• Confirm the existing fitting or measure the old part, especially on older or mixed hardware sets where nothing is standard.

• Check whether the replacement needs to match a known brand, model or finish to keep the job consistent.

• Read the product specifications to be sure the part suits the sash, the frame and the intended use.
