Iron Internal & External Letterplate offers a striking blend of classic elegance and practical robustness—perfectly crafted for those who value authentic detailing at the entrance. Designed and produced in the UK using traditional casting methods, this door fixture is available in both black iron and pewter iron finishes. It’s an ideal choice for those seeking a refined iron letter plate that stands the test of time.
This set includes both an internal and external section, ensuring a visually harmonious application with comprehensive weather protection. Option 6 is offered in two sizes:
-
Size 1: 75 mm deep × 228 mm wide × 50 mm high—suited to doors with a 70 mm leaf.
-
Size 2: 48 mm deep × 228 mm wide × 50 mm high—designed for doors with a 44 mm leaf.
The use of cast iron gives the letterplates substantial weight and tactile depth, while the hand-finished black iron variant delivers dramatic contrast against lighter doors. The pewter iron finish, on the other hand, gently reflects light with a softer, silvery tone—ideal for schemes with muted or pastel palettes.
Both finishes age gracefully, revealing nuanced patina over time rather than showing wear. Their durable nature ensures resistance to regular use and the elements, making them ideal for both traditional and contemporary builds.
Straightforward to install and thoughtfully designed, Option 6 letterplates offer both stylistic coherence and lasting quality—perfect for homeowners seeking a refined, functional detail that honours historic feel while providing modern performance.

An insight into the manufacturing process…
Made in the UK, each casting is heat‑treated to transform the iron’s structure for improved workability, then carefully fettled, assembled and protected with an anti‑corrosion finish. A hard‑wearing, oven‑cured two‑coat paint system is applied before final assembly, inspection and packaging for dispatch.
