Deadlocks: 3 Lever

Our range of 3-lever mortice deadlocks provides reliable, cost-effective security for internal residential and office doors, as well as low-risk external applications such as sheds and outbuildings. Ideal for timber doors where high-security British Standard ratings are not required, these deadlocks are available in standard UK sizes - including 64mm (2.5 inch) and 75mm (3 inch) case depths - to ensure a straightforward replacement or installation. With options from leading brands like Union, Yale, ERA, and Asec, our collection features various finishes such as polished brass, satin chrome, and stainless steel, with select models offering fire-door compatibility and Certifire approval to suit your specific safety requirements.
