In the version without edge, and larger anchorage depths, the fischer universal plug UX is suitable for push-through installation. The fischer universal plug UX is recommended, for example, for fixing lighting, curtain rails, lightweight cupboards and skirting. The fixing sets with screws, eye screws and hooks provide the optimum solution for almost all applications.

The universal operating principle (knotting or expanding) allows for use in all solid, hollow and board building materials. Thus the UX is the correct choice for unknown base materials
The UX's angled connection ridges allow for optimum screw guidance. Serrated anti-rotation locks prevent rotation in the drill hole. This guarantees the greatest possible installation safety
Fixing sets with screws, eye screws and hooks provide the right solution for all applications
