Description
The Lonsdale eurobolt provides keyed deadbolt security on a 70mm round rose to match the Lonsdale lever range. Available in single cylinder (key outside, turn-snib inside) or double cylinder (key required on both sides), it uses the same backplate profile as the Lonsdale lever set for a matched appearance across entrance doors.
The adjustable 60–70mm backset suits the majority of Australian residential door preparations without modification.
Available finishes: Brushed Nickel, Chrome Plate, Matte Black

Frequently Asked Questions
Single cylinder or double cylinder — which do I need? Single cylinder: key from outside, turn-snib from inside. Suitable for most residential entrance doors. Double cylinder: key required from both sides. Used where glass panels are near the lock and you want to prevent someone breaking glass to reach the inside turn. Check your home insurance requirements before choosing double cylinder.
