From The Anvil Matt Black Traditional Letterbox

Description

For composite and upvc doors we would recommend using our door letterbox which is supplied as a full kit and contains a tunnel and brushes to reduce drafts and insulate the door. The sleeve inside the letterbox also protects the door from moisture and masks the aperture cutting.

• Designed to match our other matt black front door furniture to create a feature entrance door.
• Maximum door thickness: 72mm.
  Minimum door thickness: 42mm.
• Supplied with matching SS bolt through fixings.

Our refined matt black finish has a distinct contemporary feel. Naturally, it looks great in ultra-modern interiors, but this versatile finish is timeless and will create a sophisticated statement in traditional or more rustic settings too.
The matt black finish is applied to a base material of solid steel and then baked in a high temperature oven, resulting in a subtle black patina that emphasises the product’s clean silhouette.
