The CELO multifunction frame plug MFR is available in diameter 8, 10 and 14 mm with different screw materials and head types. The MFR is ETA approved together with the CELO safety screw in zinc plated and stainless steel. The multifunction frame plug MFR enables universal mounting of facade substructures as well as wood and metal parts in all common base materials. The long expansion area and early expansion achieved by lateral bars ensure reliable and secure hold. All lenghts up to 160 mm are pre-assembled, this reduces costs in warehousing and saves time at the construction site. The uniform setting depth eases the installation of different plug lengths. The plug consists of high quality and ageing resistant nylon. The flat rim version prevents contact corrosion of metal parts.
