DIN Lockcases for Fire Doors & Public Access

Explore Our Range of Heavy-Duty DIN Locks

DIN Locks are trusted throughout the UK construction and fit-out industry thanks to their consistent sizing and adaptability. These lockcases are especially popular in projects involving fire-rated doors, healthcare facilities, schools, and office refurbishments where compliance with BS EN 12209 is required. The fixed 72mm or 78mm centres provide seamless alignment with modern handle furniture, while euro profile cut-outs support a wide range of cylinder types.

At Trade Door Handles, we supply a curated selection of DIN Locks in multiple formats, including privacy locks for bathrooms, escape locks for fire exits, and sashlocks or deadlocks for general security. Choose from a wide range of finishes to suit your scheme, including Matt Black, Aged Brass, Satin Stainless Steel, Polished Chrome, and more.

To complete your installation, pair these lockcases with high-quality door furniture including handles and escutcheons. For compliant fittings and design flexibility, explore our architectural ironmongery collection — ideal for commercial and public sector projects. You can also add finishing touches using our range of premium accessories, which includes items like fixings, indicators, and replacement faceplates.

Need Technical Advice?

Contact Us for Help Choosing the Right DIN Lock

Choosing the correct DIN lock depends on a few key factors — including the door's application (bathroom, corridor, fire escape), the type of handle or cylinder you’re using, and whether the lock needs to meet fire safety or accessibility standards.

DIN Locks come in various backsets and centre measurements, so selecting the right combination is essential to ensure proper function and compliance. We regularly help contractors, facilities managers, and joiners across the UK who are working on commercial projects in offices, hospitals, schools, retail units, and more.

If you’re unsure about compatibility with lever-on-rose handles or need guidance on DIN euro profiles, sashlocks, or escape function locks, our experienced team is here to help. Whether you're sourcing fire door hardware or refitting a public building, we provide practical advice on everything from dimensions to finishes.

For personalised support, please contact us and a member of our team will guide you through your options and help you choose the most suitable DIN lock for your installation.

Frequently Asked Questions

DIN Lock FAQs

Are DIN Locks fire-rated?

Many DIN Locks are tested to EN standards, making them suitable for FD30/FD60 fire door assemblies in schools, offices, and healthcare facilities.

Do DIN Locks fit UK doors?

Yes, provided you use compatible euro cylinders and lever-on-rose furniture. They are not designed for traditional UK backplate handles.

What is the difference between DIN sashlocks and deadlocks?

Sashlocks include both a latch and deadbolt, operated by a handle and key. Deadlocks only include a key-operated bolt and are ideal for additional security.

Are alternative faceplates available?

Yes. Although Satin Stainless Steel is standard, many of our DIN locks are available in finishes like Aged Brass, Black, Antique Bronze, and more.
