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.
Our polished chrome products are made from a base metal of solid brass with a high quality chrome plating applied to the surface. A high sheen finish that is most commonly used in contemporary settings. This finish offers bright, bold and reflective qualities which work best if a clean, cool look is desired.
We recommend avoiding the use of any chemicals or cleaning products on this finish as it may affect the plated finish. An oily cloth can be used to wipe over the product from time to time to remove any harmful deposits that build up on the surface of your product, this will also aid protection against any environmental elements. A dry cloth can also be used to wipe over the product and reduce finger marks. Regular oiling of all moving parts using our ‘3-in-1 Oil’ (92337) is beneficial to the longevity of your products. This process is also highly recommended during initial installation.
