For composite and upvc doors we would recommend using "From The Anvil" 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 "From The Anvil" other aged brass front door furniture to create a feature entrance door.
Maximum door thickness: 72mm.
Minimum door thickness: 42mm.
"From The Anvil" aged brass products are made from solid unlacquered brass, offering an abundance of character and charm. This finish is perfectly suited to period dwellings and will create a statement throughout. Due to the accelerated ageing process this finish undergoes, a darker patina gathers around the edges and recesses to contrast beautifully with the re-polished surface areas.
