NBNP 90mm Cylinder Lock, Euro Profile, Double Keyed, Satin Silver

90mm Euro Profile Cylinder

The NBNP 90mm Cylinder Lock provides a robust security solution for commercial and residential doors requiring a standard Euro-profile configuration. This double-keyed unit allows for entry and locking operations from both sides of the door. It fits standard mortice lock cases designed for 90mm profile cylinders.

Built for the Job

Facility managers and locksmiths specify this 90mm hardware for doors with a thickness ranging from 55mm to 75mm, depending on the handle offset. The symmetrical 45/45 split ensures the locking cam aligns accurately with the internal mechanism of the mortice case. It handles high-traffic environments where consistent mechanical reliability is required. This specific length often suits fire-rated timber doors or heavy-duty aluminum shopfront sections that utilize thicker infill panels.

• Installation in external timber doors where double-sided key access is mandatory for security protocols.

• Retrofitting existing commercial aluminum doors that use standard Euro-style locksets.

• Securing utility rooms or storage areas within multi-tenant facility complexes.

On-Site & Workshop Notes

• Always measure from the center of the fixing hole to both edges of the door to confirm the 45/45 split matches your door thickness.

• Lubricate the internal pins annually with a graphite-based lubricant rather than oil to prevent dust accumulation and sticking.

• Ensure the cam is rotated slightly during installation to allow the unit to slide through the mortice lock case without obstruction.

• Tighten the fixing screw by hand to avoid stripping the threads in the cylinder body during final assembly.
