📘 FAQs – Mortice Door Knobs

❓ What is a mortice door knob?

A mortice door knob is a turning knob that works with a mortice latch fitted inside the door. It usually requires a deep backset latch to allow comfortable turning and avoid catching your knuckles on the door frame.

❓ What's the difference between sprung and unsprung knobs?

• Sprung knobs have an internal spring to return the knob to its original position.

• Unsprung knobs rely on the latch for return tension, and are best used with a heavy-duty sprung latch.

❓ Do I need a special latch for mortice knobs?

Yes – you should use a deep latch (typically 76mm–100mm) so the knob sits far enough from the door edge to operate comfortably.

❓ Can mortice knobs be used on bathroom doors?

Yes – pair them with a bathroom mortice lock or use a turn & release set on the opposite side for privacy.

❓ Are they suitable for fire doors?

Some mortice knobs are fire-rated, but only when used with FD30 or FD60 rated latches and the appropriate intumescent materials.

❓ Can I use these knobs on old doors?

Absolutely – they’re often chosen for period homes or restoration projects, and work well with rim locks or traditional mortice latches.
