Strong contemporary appeal in a Matt Black Mushroom Mortice Knob

The Mushroom Mortice Knob in Matt Black introduces bold urban style to any interior. Because the finish absorbs light softly, it creates deep, expressive tones without harsh reflection. The rounded mushroom shape feels smooth and balanced in the hand, and its clean outline suits both modern and traditional rooms. This combination brings instant sophistication and architectural elegance to your doors.

Solid brass structure with smooth, reliable turning

Although the surface is matt black, the knob is crafted entirely from solid brass. This ensures strength, reassuring weight and long-term reliability. Every turn feels smooth and controlled. Because matt black hides fingerprints naturally, it maintains an even tone with minimal care. Over time, the surface remains velvety and consistent, even through everyday use.

This Harrogate design pairs effortlessly with a variety of dark-toned finishes. It coordinates perfectly with the Matt Black Old English range.
It also blends beautifully with reflective tones in the Black Nickel collection.
For an industrial touch, it works smoothly with the Matt Gun Metal range.
These combinations allow you to create a unified, contemporary look throughout your home.

Easy installation with flexible door pack choices

Installing your Mushroom Mortice Knob is simple, and the three door packs ensure you have everything required for a complete setup.

  • Latch Pack (3” or 4”) – Ideal for doors that do not require a lock.

  • Bathroom Pack (3” or 4”) – Includes a latch, deadbolt and turn & release for privacy.

  • Lock Pack (3” only) – Offers a secure 3-lever deadlock, keys and matching escutcheons.

You also have the choice of Grade 7 fire-rated hinges or Grade 13 fire-rated hinges, both supplied in packs of three. These hinge options provide strength, smooth movement and suitable safety standards.

Matt black finish with expressive modern style

Matt black is a distinctive finish appreciated for its boldness and versatility. Because the surface diffuses light gently, it brings calm tonal depth ideal for modern interiors. Inspired by Bauhaus architecture, wrought iron detailing and traditional blacksmith work, the finish bridges contemporary and heritage styles effortlessly. It works beautifully in minimalist homes, industrial spaces, monochrome designs and rustic-modern interiors.
