A mushroom mortice knob with rich bronze character

The mushroom mortice knob from the Old English Harrogate range brings soft curves and deep tone to any room. Its rounded profile feels smooth and comfortable. Because the knob is made from solid brass, it offers a warm, balanced weight in hand. The Urban Dark Bronze finish adds richness with subtle shading, which suits modern spaces, rustic interiors and everything in between.

Premium brass construction for a refined mushroom mortice knob

This mushroom mortice knob uses solid brass throughout, so it stays strong with daily use. The concealed rose hides all screws, which keeps the shape clean. The turning action feels steady and smooth. The dark bronze tone adds depth and works beautifully with natural materials like wood and stone, giving your home a grounded, elegant feel.

Dimensions

  • Knob Diameter: 57mm

  • Rose Diameter: 60mm

  • Projection: 73mm

  • Spindle: 8mm

Pack options to suit your mushroom mortice knob

You can choose the best pack for your door.
The Latch Pack includes knobs, a latch and hinges for standard rooms.
The Bathroom Pack adds a turn and release with a deadbolt for privacy.
The Lock Pack includes a 3-lever deadlock, two keys, escutcheons, a latch and hinges for added security.
Each pack provides a coordinated finish, so your door looks and feels complete.

Hinge styles that complement the mushroom mortice knob

You can select from two hinge types to support your door.
Grade 7 Fire-Rated Hinges suit everyday internal doors.
Grade 13 Fire-Rated Hinges support heavier doors and add extra strength.
Both hinge packs include three hinges and match the weight of this solid brass knob.

Urban Dark Bronze that elevates your mushroom mortice knob

Urban Dark Bronze has a rich, contemporary tone that warms a room instantly. The soft matte surface brings depth without overpowering your décor. It pairs well with dark woods, muted palettes and modern natural finishes. For a coordinated look, you can match this knob with the Old English Kendal Door Handle – Urban Dark Bronze, which shares the same deep bronze tone and refined brushed texture.
