DIN Latch Product Breakdown

What Makes DIN Latches Ideal for UK Commercial and Residential Projects?

DIN latches are the preferred solution for internal doorways in offices, schools, hotels, and apartment blocks. Their robust construction and consistent dimensions make them ideal for volume-based installations where door handle alignment, fire rating, and interchangeability matter.

Available in 60mm or 80mm case depths, these latches are commonly specified by contractors and architects working to EN12209 and BS EN standards. Whether upgrading a high-traffic corridor or specifying for new builds, DIN latches support seamless integration with DIN Bathroom Locks, DIN Escape Locks, and DIN Euro Sash Locks.

Specifications and Practical Considerations

How to Choose the Right DIN Latch

When selecting a DIN latch, consider door thickness, latch depth, and handle design. These latches are compatible with fire-rated doors and high-performance architectural ironmongery, typically requiring a rectangular mortice and a rose-mounted handle set.

Frequently Asked Questions

DIN Latch FAQs

What does DIN mean on a latch?

DIN stands for Deutsches Institut für Normung — the German body that sets hardware standards. A DIN latch follows fixed dimensions for consistent installation on commercial and fire-rated doors.

Are DIN latches suitable for fire doors?

Yes. Most DIN latches are tested to EN12209 and EN1634-1 and are ideal for FD30 or FD60 fire doors. Always check that the latch is CE marked and correctly certified.

What is the difference between a DIN latch and a tubular latch?

A DIN latch offers superior durability, fire certification, and standardised dimensions. A tubular latch is quicker to install and cheaper, but not usually fire-rated. For more, visit our Tubular Mortice Latch collection.

Do DIN latches lock?

No — DIN latches are non-locking. If you need a secure locking version, consider using a DIN Night Latch or DIN Euro Sash Lock, which provide added key or thumbturn control.
