DIN lock buying guide

What is a DIN lock?

DIN lock cases follow the European standard for dimensions and fixings, making them a reliable, standardised replacement. Most take a euro cylinder for the keyed function.

How do I choose the backset and centres?

Check the backset from the door edge and the 72mm cylinder-to-follower centres typical of DIN cases, so your handles and cylinder line up.

Do I need intumescent protection?

On fire doors, fit an intumescent kit behind the lock case to help maintain the door's fire rating.
