We accompany and advise you on your choice of various surfaces and materials (such as stainless steel, aluminium or galvanized steel sheet). Whether you prefer letterboxes with standard flaps, bigger letter flaps or with a soft-close-function, the choice is yours. SKS offers different locks as well as a selection of name plates. Individual cladding, plaster cover frames and frameworks make your letterbox system unique. Moreover, further communication elements such as loudspeaker grids, doorbell buttons and additional backlighting of the doorbell buttons are available.
All our letterboxes comply with the current EN-Norm 13724.
