Frequently Asked Questions

Will this match my square rose Lonsdale levers? Yes, provided you match the finish. The 64x64mm square backplate is designed to complement the Lonsdale square lever rose.

Single cylinder or double cylinder? Single cylinder uses a key outside and a turn-snib inside — the most common residential choice. Double cylinder requires a key on both sides, suited to doors adjacent to glass panels where inside access via breakage is a risk.

Is professional installation available? Yes. Lockmart's qualified locksmiths can install this hardware at your Melbourne property. Contact us to arrange a quote.
