Nidus Lonsdale Square Eurobolt Double Cylinder 63x63mm

Secure, Sleek and Specification-Ready

The Nidus Lonsdale Square Eurobolt Double Cylinder is a refined security solution designed for front and rear external doors where elevated protection and architectural consistency are essential. Featuring a keyed cylinder on both sides, this lock allows entry and locking control from either side of the door, making it ideal for residential and light commercial applications.

With its square rose design and minimalist geometry, the Lonsdale Eurobolt complements modern hardware selections while maintaining a strong architectural presence. It pairs seamlessly with the broader Lonsdale lever range, allowing designers and specifiers to achieve visual consistency across entry and internal doors.

Available in a 60mm backset with a compact 63x63mm backplate, the Eurobolt is engineered for straightforward installation into standard door preparations. The lock can be keyed alike or keyed to differ, providing flexibility across multi-door projects. Simply note your preference at the time of order.

Offered in a selection of architectural finishes—Matt Black, Brushed Nickel, and Chrome Plate—the Lonsdale Eurobolt is built to meet the design and durability expectations of today’s architectural specifications.
