What is a mortice lock or latch and when should I use one?

Mortice locks and latches fit inside the door edge for a clean look and secure fixing. Use sashlocks where a handle and latch are needed, deadlocks for key security, and latches for internal passage doors.

What is the difference between sashlocks, deadlocks and latches?

A sashlock combines a latch (worked by the handle) with a key-bolted deadbolt. A deadlock is just the key-bolted bolt. A latch has no bolt—only a sprung latch to keep the door closed.

Which Carlisle Brass option suits external doors?

Choose a BS-rated 5-lever sashlock or deadlock, or a Euro profile mortice case with a tested cylinder. These provide higher security and are often requested by insurers.

What sizes are available for mortice locks and latches?

Common case sizes are 2.5 inch and 3 inch. Match the backset and follower to your handles and door prep, and add the correct rebate set for rebated double doors.

Are these suitable for certified fire doors?

Many Carlisle Brass and EuroSpec models have fire-tested variants. Use the specified intumescent kits and compatible hardware to maintain certification.

Do you deliver across the UK?

Yes—orders are fulfilled with quick nationwide delivery across the UK.

Who are Carlisle Brass and why choose their architectural ironmongery?

Carlisle Brass is a leading UK brand in architectural ironmongery established in 1986, known for quality door furniture, window fittings, hinges, and locks & latches. Many product families are manufactured to exacting standards, with ranges designed for homes, hotels, and commercial projects. Choosing Carlisle Brass helps ensure consistent design across handles, accessories, and ancillary hardware.

Which finishes are available in the Carlisle Brass range?

Popular finishes include Polished Brass, Polished Chrome, Satin Chrome, Satin Nickel, Polished Nickel, Antique Brass, Matt Black, and Satin Brass. Heritage and project finishes are also available such as Ludlow Antique Black and stainless-steel grades for commercial environments. These finishes make it easy to coordinate door handles, knobs, hinges, locks, and matching accessories.

Are Carlisle Brass handles and accessories suitable for fire doors?

Many Carlisle Brass products have versions suitable for fire doors when used with the correct intumescent materials and compatible latches/locks/hinges. Always check the individual product specifications for fire ratings, CE/UKCA markings, Certifire (where applicable), and follow the door manufacturer’s guidance. For help pairing compliant hinges, closers, and locks, contact our team.

How do I choose the right lock or latch (Euro cylinder vs 3/5-lever, backset sizes)?

For external doors, Euro profile locks with a cylinder are popular; for traditional setups, 3-lever (internal) or 5-lever (external) sash and deadlocks are common. Measure the backset (edge of door to spindle/centre) and case size to match existing cut-outs—typical UK latch case sizes are 64 mm or 76 mm. Bathroom turns need a bathroom lock or separate deadbolt. Ask us if you’re unsure and we’ll guide you.

How do I measure for replacement door handles, knobs, or hinges?

Measure spindle size (usually 8 mm), the lock/latch backset, and if replacing a backplate handle, note screw hole centres and plate size. For hinges, confirm leaf size, thickness, and bearing type; fire doors typically require 3 graded hinges. For roses and knobs, check door thickness and clearance to architraves. Share a photo and measurements for tailored advice.

Do Carlisle Brass offer matching switches and sockets?

Yes—complementary decorative electrical accessories are available via the EuroLite range, allowing you to coordinate door furniture with matching switch and socket finishes across your project.

Do you deliver Carlisle Brass products across the UK?

Yes. We provide a quick nationwide delivery service across the UK, including London, Manchester, Birmingham, and our local areas of Kendal, the Lake District, and Carlisle.

Which sub-brands sit within the Carlisle Brass portfolio?

Key sub-brands include Serozzetta (contemporary levers), Fingertip Design/FTD (cabinet hardware), EuroSpec (project/commercial hardware), Delemain (traditional knobs), Manital (Italian premium designs), EuroLite (decorative electrical), and Alexander & Wilks (luxury solid brass hardware).

How should I care for Carlisle Brass finishes?

Wipe with a soft damp cloth and dry immediately. Avoid abrasive cleaners, bleach, and solvent polishes. For lacquered or PVD finishes, follow the product guidance; on coastal or high-traffic doors, clean more frequently to preserve the appearance.

Mortice locks and latches explained

Choosing the right Carlisle Brass mortice lock or latch for your door

Mortice locks and latches are fitted within the edge of a door, offering a neat appearance and long-term reliability. Each type serves a specific purpose depending on where it’s installed:

Entrance Doors

Opt for a BS-rated 5-lever deadlock or sashlock for strong external door security.

Alternatively, a Euro profile mortice case with a matching cylinder is ideal for master key systems and commercial settings.

Internal Doors

For rooms that don’t need key locking, use a mortice latch paired with a lever handle.

Bathrooms and WCs should have a bathroom lock or deadbolt for safety and convenience.

Commercial & Project Use

When fitting to offices, schools, or hotels, choose DIN-pattern cases that meet commercial standards and allow for consistent sizing across multiple doors.

Double & Fire Doors

Use the correct rebate set for rebated double doors to ensure a proper fit.
Where fire certification is required, always pair the tested lock or latch with matching intumescent kits and compatible hardware.

Quality & Application

Carlisle Brass offers case grades ranging from value to heavy-duty, suitable for:

Homes and rentals
Hospitality and leisure projects
Education and healthcare environments
