Spira Brass Connaught Knurled Door Knob - Gold

The Spira Brass Connaught Knurled Door Knobs are made from high-quality solid brass.

These are unsprung knobs and are designed to be used with a mortice lock mechanism that is also unsprung or has sufficient spring strength.

The knob diameter is 55mm, and the rose diameter is 60mm.

While made of solid brass, they are best suited for interior doors. For exterior doors, consider hardware specifically designed for weather resistance.

Clean with a soft, damp cloth. For best results and to maintain shine, use a specific brass polish occasionally, applied with a soft cloth.

The knobs are designed to be fitted onto a standard mortice lock spindle and use the fixings provided with the mortice lock itself. The knobs attach to the spindle.

The knobs have a protrusion of 55mm from the door surface.

Ensure the grub screws on the knob's collar are tightened securely onto the mortice lock spindle. Check that the spindle is correctly inserted into the lock.

Verify that the mortice lock mechanism is functioning smoothly. The knob itself is usually not the cause of stiffness; the issue often lies with the lock mechanism or the spindle alignment.

Clean the knob with a soft, damp cloth. For tarnishing, use a dedicated brass polish and a soft cloth, following the product's instructions. Ensure the lock is engaged properly before polishing.

This typically indicates an issue with the mortice lock's spring mechanism. Check if the lock is sprung or unsprung, and ensure it is compatible with the unsprung nature of these knobs.
