Pro-Skirt Flat is a model of aluminium skirting that combines simplicity and decorative appearance with angular sharp lines. Thanks to the base apparatus which can be placed and mounted on the wall surface it can be easily applied. The backrest can be easily assembled either by a combination of an anchor and a screw selected according to the surface to be applied, or with a suitable mastic. As a result of Protrim R&D works the return apparatus can be used in all inner and outer corners as well as right and left ends. Combined with the design of Pro-Skirt-Flat this simple and innovative application provides easy application and an integrated look. It is represented as an aesthetic detail in every area of life such as schools, hospital, housing, offices and shopping centres.
