The fischer UX universal plug is a plastic plug made of high-quality polyamide. The fischer universal dowel spreads in solid construction materials and knots in hollow and plate construction materials for maximum support. This means that fischer UX is always the right choice – even for an unknown building material. The edge prevents slipping during mounting. In the version with an edge, the fischer UX universal plug is suitable for pre-plug mounting. The fischer UX universal plug is recommended, for example, for fixing lights, curtain rails, light cabinets, and baseboard.
