Mortice door knobs are designed specifically for use with mortice locks and are not suitable for rim lock applications. The door knobs in this category are intended for internal or external door setups where the lock mechanism is housed within the door itself, providing a clean, traditional finish with reliable everyday performance.
The backplates on these knobs are fixed and cannot be removed, meaning they cannot be adapted for use with a rim lock. This ensures a solid, stable installation when paired with a mortice lock and helps maintain correct alignment and long-term durability once fitted.
