The Spira Brass Ribbed Rim and Mortice Door Knob in Bronze is an ideal choice for homeowners and interior enthusiasts looking to restore or enhance Regency and Georgian-style spaces with authentic antique aesthetics. These high-quality brass knobs provide a sophisticated, tactile finish to wooden doors, though users should note that they are an unsprung design, which requires a latch or lock with strong internal spring assistance for optimal operation.

While durable, these are primarily designed for interior use. Using them outdoors may result in faster oxidation of the bronze finish.
The knobs themselves are simply handles. The locking functionality depends on the mortice latch or rim lock you choose to pair them with.
The knob and rose diameter is 50mm.
Please check your local fire safety regulations; generally, fire doors require specific certified hardware that may differ from decorative brass sets.
No, the set is supplied as a pair and includes all necessary fixings and components for a standard installation.
These knobs have a 62mm protrusion from the surface of the door.
Tighten the grub screws securely and ensure the spindle is correctly aligned within the knob set.
The design is unsprung; verify that your mortice latch or rim lock has a sufficiently strong internal spring to facilitate the return action.
Check that the door is correctly aligned in the frame and ensure the spindle is not over-tightened against the lock mechanism.
For installation, ensure you have a standard screwdriver and measuring tape. As an unsprung knob, check that your chosen latch or lock is designed to support the weight of heavy brass furniture. If installing on an existing door, confirm that the 50mm rose covers any previous markings or wear. To maintain the bronze finish, wipe periodically with a soft, lint-free cloth dampened with mild soapy water and buff dry. Avoid using harsh chemical cleaners or abrasive sponges, as these can strip the protective finish and lead to oxidation.
