3 Lever Sashlock – Satin Nickel (78mm Case / 58mm Backset)
A medium security mortice sashlock designed for internal and light external timber doors in domestic and commercial buildings. The 3 lever mechanism and medium duty spring make it ideal for bedrooms, storerooms and general access doors where keyed security is required, while the satin nickel finish provides a clean, contemporary look that coordinates with modern door furniture.

- 78mm case depth with 58mm backset to follower – ideal where a deeper lock position or additional handle clearance is required.
- Reversible latch bolt for left- or right-handed doors.
- Satin nickel square faceplate and keep for a neat, durable, contemporary edge detail.
- Supplied with 2 keys, strike plate/keep and fixing screws.
