Do Carlisle Brass letter tidies come with a warranty?

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.
