About M.Marcus window furniture

M.Marcus is a long-established British hardware manufacturer whose window fittings are trusted by joiners, builders, and homeowners across the UK. Within this range you will find hardware from the popular Heritage Brass and The Tudor Collection sub-brands, so you can match window furniture to door handles, hinges, and other architectural ironmongery for a consistent look throughout a property. The emphasis throughout is on traditional design, solid construction, and finish consistency.

Casement window furniture

For timber casement windows, choose from casement stays in the popular ball design, available in 8 inch (200mm), 10 inch (250mm), and 12 inch (300mm) lengths to suit different window sizes. Pair a stay with a matching casement window fastener, offered in both mortice and hook plate and wedge styles, to hold the window securely closed. Casement stay pins and lockable casement stay locking pins add extra security and let you set the window at a fixed opening. These traditional casement fittings are a straightforward upgrade for period and heritage properties.

Sash window furniture

For box sash and vertical sliding windows, the range covers Brighton sash fasteners, Fitch sash fasteners, and quadrant sash fasteners to lock the meeting rails together. Sash lifts and sash rings make raising and lowering the lower sash easier, while locking sash window stops with a key allow a window to be held part-open for ventilation without compromising security. These sash window fittings suit Georgian, Victorian, and Edwardian homes as well as modern reproductions.

Espagnolette window handles

Lockable espagnolette window handles operate multi-point locking espagnolette rods on tall casement and French-style windows, and are available in left hand and right hand versions along with reeded designs. They combine period styling with practical, key-locking security.

Finishes to match your existing ironmongery

Coordinate your window hardware across a whole project with a wide choice of finishes, including Polished Chrome, Satin Chrome, Polished Brass, Satin Brass, Antique Brass, Unlacquered Brass, Polished Nickel, Satin Nickel, Matt Black, Antique Black, Matt Bronze, Rustic Pewter, and Rustic Dark Bronze. Matching finishes across window furniture, door handles, and hinges gives a clean, considered result in both traditional and contemporary interiors.

Materials and build quality

M.Marcus window furniture is manufactured predominantly from solid brass, giving each fitting a reassuring weight, smooth operation, and durability that stands up to daily use. Quality plating and lacquering help protect the finish and keep hardware looking its best over years of service, which makes this range a sound choice for restoration work where longevity matters.

Buying and fitting tips

When replacing existing window furniture, measure your current hardware, including centre-to-centre fixing points where relevant, and confirm your window type: casement, box sash, or fanlight. If you are matching a finish across several windows, order all your fittings together to keep finish batches consistent. Not sure which fastener or stay you need?
