Nidus Eurobolt Square Rose Deadbolt

The square rose eurobolt is the matching deadbolt for Nidus square rose lever sets. The square backplate profile gives a more contemporary, architectural look than the round rose version, and pairs directly with the Lonsdale square rose lever set for a consistent external door presentation.

Adjustable 60–70mm backset and 54mm crossbore compatibility make it a straightforward fit for standard Australian residential door prep.

Available finishes: Brushed Nickel, Chrome Plate, Matte Black, Satin Brass
