📘 FAQs – DIN Standard Locks and Latches

❓ What does "DIN standard" mean in door hardware?

DIN (Deutsches Institut für Normung) standards are German industrial norms used across Europe to ensure consistent sizing and compatibility for locks and ironmongery.

❓ What’s the benefit of DIN standard locks?

They allow for interchangeability, making it easy to replace or upgrade locks without adjusting the door prep. They're especially useful in commercial or fire-rated installations.

❓ What’s the difference between DIN and UK standard locks?

DIN locks usually have larger case sizes and standard 72mm or 78mm centres (distance between spindle and keyhole/turn), while UK locks often have 57mm or 48mm centres.

❓ Are DIN locks fire rated?

Yes – many DIN locks are fire-rated and CE marked, making them suitable for use on FD30 or FD60 fire doors when paired with appropriate hardware.

❓ Can I use DIN locks in residential homes?

Absolutely. While commonly used in commercial environments, DIN locks offer durability and a clean aesthetic ideal for modern homes, especially with euro cylinders and lever handles.

❓ What types of DIN locks do you offer?

We stock DIN mortice latches, deadlocks, bathroom locks, escape function locks, and more, in multiple backset and finish options.

❓ What’s an escape function lock?

This type of DIN lock allows the door to be opened from the inside at all times, even when locked from the outside – ideal for fire exit and safety applications.
