Pro Tips:

Pro Tip: Before applying the adhesive-backed foam weather seal, thoroughly clean and dry the door sash surface to ensure optimal adhesion. The peel-off backing makes installation straightforward, but correct positioning on the first attempt is important as repositioning may compromise the seal's effectiveness. For installations within 25 miles of coastal areas, increase maintenance frequency to monthly cleaning with warm water and mild detergent. The Grade 4 corrosion resistance provides excellent protection, but regular removal of salt deposits and atmospheric contaminants will maximize the lifespan of the electroplated finish. Apply light non-acidic mineral oil to the flap hinge twice yearly to maintain smooth operation.

Frequently Asked Questions:

Which variant do I need for my door?

The 20mm-40mm variant is designed for panel and composite doors, which typically have thinner door slabs. The 40mm-80mm midrail variant is specifically designed for uPVC doors and thick door profiles. If you're unsure, measure your door thickness at the Letter Box position. Panel and composite doors usually measure between 20mm-40mm, whilst uPVC doors typically measure 40mm-80mm. Choosing the correct variant ensures proper fit and optimal weather sealing performance.

Will this Letter Box fit my uPVC or composite door?

This ERA letter plate is available in two variants to suit different door types: the 20mm-40mm variant is designed for panel and composite doors, whilst the 40mm-80mm midrail variant suits uPVC doors and thick door profiles. The Letter Box measures 291.5mm long × 72.5mm high externally and requires a minimum aperture of 264 x 48mm. Measure your door thickness to confirm which variant you need. The 270mm fixing centres match standard door preparations. If you're replacing an existing Letter Box, measure your current fixing hole centres to confirm compatibility. The aperture is designed to accommodate standard UK mail sizes including large letters and small parcels.

How do I maintain the finish in coastal areas?

While the Letter Box meets BS EN 1670 Grade 4 corrosion resistance (240 hours salt spray testing), coastal installations require monthly cleaning with warm water and mild detergent to remove salt deposits. Avoid chlorine or potassium-based cleaners which can damage the electroplated finish. Apply light non-acidic mineral oil (such as "3 in 1") to moving parts twice yearly. More frequent cleaning prevents accumulation of corrosive contaminants that can affect appearance over time.

What's the difference between the finish options?

Chrome and Polished Gold both use electroplated coating, offering reflective, premium appearances suited to modern and traditional styles respectively. White and Black finishes provide colour-matched options for uPVC and composite doors. All finishes provide equivalent corrosion protection, with each meeting the same BS EN 1670 Grade 4 standard for long-lasting durability.
