The CELO multifunction frame plug MFR is available in diameters of 8, 10 and 14 mm with different screw materials and head types. MFR is ETA approved together with CELO safety screw made of galvanized and stainless steel. The MFR multifunction frame plug allows universal mounting of façade bases as well as wooden and metal parts in all common basic materials. The long expansion area and the early expansion achieved by the side bars ensure reliable and secure holding. All lengths up to 160 mm are pre-assembled, which reduces storage costs and saves time on site. Uniform setting depth makes it easy to install plugs of different lengths. The plug is made of high quality and aging-resistant nylon. The flat arc version prevents corrosion of metal parts.
