3 Lever Deadlock – Electro Brass (78mm Case / 58mm Backset)

A medium security mortice deadlock designed for internal and light external timber doors in domestic and light commercial buildings. The 3 lever mechanism provides reliable keyed security where a full British Standard 5 lever lock is not required, while the electro brass finish gives a neat, traditional look that complements classic door furniture, especially where a deeper lock position is needed.
