NBNP 62mm Cylinder Door Lock, Antique Brown Finish

NBNP Antique Brown Cylinder

The NBNP 62mm Cylinder Lock serves as a reliable security core for standard timber and metal doors in residential or commercial settings. This 62mm profile unit provides a mid-range length suitable for doors approximately 40mm to 45mm thick. The hardware features a corrosion-resistant antique brown finish to match vintage or decorative door furniture suites.

Built for the Job

Site supervisors and locksmiths specify this cylinder for its straightforward installation and compatibility with standard Euro-profile mortice locks. The 31mm/31mm split ensures the cam sits centrally in most standard door thicknesses. This prevents the cylinder from protruding excessively beyond the escutcheon or handle plate. The brass internal construction resists the mechanical fatigue common in high-traffic entry points.

• Retrofitting existing mortice locks during building renovations.

• New installations on internal office or residential bedroom doors.

• Matching hardware for antique-themed interior design projects.

On-Site & Workshop Notes

• Measure the distance from the center of the lock body to the outer edges of the door before fitting this barrel.

• Avoid using heavy oils for maintenance; a dry graphite spray keeps the tumblers moving freely without attracting dust.

• Ensure the cam is aligned correctly with the mortice lock drive before tightening the center fixing screw.

• The antique brown finish should be cleaned only with a soft damp cloth to preserve the protective coating.
