Satin Marine SS (316) Traditional Letterbox

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 satin marine SS 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 Satin Marine Stainless Steel is grade 316 and manufactured with high concentrations of chromium and nickel. These products offer great strength and have extremely resilient corrosion resistant properties which make them an excellent choice for coastal locations. This finish is low sheen and offers a frosted, matt look. For complementary products, we recommend our Satin Chrome finish.

This finish is designed to be maintenance free and offers exceptional protection against corrosion.  Surpassing 1000+ hours salt testing, it is a perfect choice for use in salt rich or heavily polluted environments. Despite the natural durability of this finish, we would still recommend washing your product using a soft, clean cloth and mild soapy water from time-to-time to reduce unnecessary pollutants building up on the products surface.  Please ensure all products are dried immediately with a clean, soft cloth after any cleaning.

To increase the mechanical life expectancy of your product, we recommend oiling of all moving parts using our ‘3-in-1 Oil’ (92337) periodically and during initial installation.
