Technical Guidance for Fitment

Need Advice on Installation or Compliance?

Choosing the right flat latch isn’t just about picking the right size—it’s about making sure everything fits and functions properly. Whether you're working with a 76 mm or 101 mm backset, fitting into a fire-rated door, or matching with unsprung lever handles, we can help.

Our team has over 40 years of experience in the trade and can advise on latch size based on door thickness, stile depth, and handle type. For example, a 101 mm backset is often preferred when using mortice knobs or lever handles on a rose to give more hand clearance.

We support joiners, fitters, and contractors across the UK—from Birmingham and Manchester to Glasgow and Cardiff—with straightforward technical advice. If you need help choosing the right latch for your project or making sure it meets fire door regulations, get in touch and we’ll be happy to assist.

Frequently Asked Questions

Which backset should I choose for thicker panel doors?

Use 101 mm or a longer backset to maintain clearance for handles and ensure ease of use.

Are there flat latches compatible with fire doors?

Yes—we offer options that meet BS EN 12209 and are CE or Certifire rated for FD30/FD60 applications.

How does a bolt-through flat latch improve durability?

It allows handles or knobs to secure through the latch body, reducing handle slippage or loosening over time.

Is a flat latch suitable for retrofitting on modern doors?

Only if the door edge accommodates the wider profile. If not, a tubular latch may be more appropriate.

What finishes are available to match heritage hardware?

We offer Mortice Flat Latches in Electro Brass, Satin Chrome, and Satin Stainless Steel as standard — ideal for both traditional and modern interiors. For specialist projects, we also provide a bespoke service, including made-to-order latch cases and faceplates from trusted British manufacturers. If you're working on a period property or need something specific to match existing ironmongery, get in touch to discuss your requirements.
