If you’ve ever stood in front of a wall wondering which plug to use, the Fischer DuoPower Wall Plug takes the uncertainty out of the job. 

Its dual-material construction combines a rigid grey nylon body with flexible red expansion wings. Together, they intelligently adapt to the base material: expanding in solid brick, folding in hollow blocks, or knotting in plasterboard.

The result? A single plug that works almost everywhere, giving you strong, vibration-resistant fixings without carrying multiple product types. The 8 x 40 size is especially versatile for medium-duty applications like shelving, brackets, lighting, bathroom fittings, and electrical installations.

With a load capacity of up to 110 kg in concrete and 62 kg in solid brick, the DuoPower 8 x 40 provides peace of mind for both professional trades and serious DIY projects. The narrow plug rim prevents slipping into the drill hole, while anti-rotation serrations keep it firmly in place during screw insertion.

Whether you’re fitting kitchen cabinets, mounting radiators, or securing fixtures in mixed substrates, this plug delivers consistent results and reduces call-backs.
