Review: the best - These wall plugs are amazing and super secure. If you live in a tenement flat with concrete/brick walls these are a must and will hold up shelves and anything you need like towel rails and everything without you needing to worry about them collapsing or crumbling or coming loose because they really do be gripping hard. Honestly my go to wall plugs
Review: Heavy items? Look no further. - I recently ordered the Fischer DuoPower 12 x 60 S and they arrived right on time via a smooth delivery. If you are doing any serious DIY or home improvement, these are a must-have in your toolbox. What I liked: • Superior Hold: These DuoPower plugs are incredibly versatile and provide a much more secure grip than standard plastic plugs, especially for heavier items. • High Quality: You can feel the German engineering in the 2-component design; they expand perfectly into the wall material. • Convenient Sizing: The 12 x 60mm size is perfect for larger projects that require a bit more "bite" and stability. • Great Experience: From the easy ordering process to the quick delivery right to my door, everything was seamless. Highly recommended for anyone who wants peace of mind that their fixtures aren't going anywhere!

## Features

- Highest load transfer & intelligent function: The DuoPower is the first plug that adjusts itself automatically to the respective substrate, transfers the highest loads through the three product functions of folding, expanding and knotting and thus enables a wide range of applications in solid, perforated and panel building materials. The supplied screws are perfectly machted to the plugs
- All-in-one solution for all building materials: The intelligent 2-component plug ensures top load values – the grey component automatically activates the optimal operating principle depending on the respective building material, while the expansion wings of the red component support safe spreading
- Absolutely powerful: Due to its compact and short length, the plug requires significantly less drilling effort and thus shorter screws – when installing the plug, the narrow plug rim stops it from slipping into the borehole while the anti-rotation feature prevents rotation into the drillhole, and the feel-good factor exactly indicates when the plug is installed perfectly
- Areas of application: The powerful plug is suitable for attaching light wall shelves, mirror cabinets, curtain rails, hanging baskets, electronic devices or wall clocks in various building materials such as concrete, lightweight concrete, solid and perforated bricks, natural stone, solid sand-lime bricks, perforated sand-lime bricks, gypsum plasterboard and fibreboard

### ⭐⭐⭐⭐⭐ good sturdy plugs used them for monitors and tvs.
*by F***R on 4 January 2026*

good plugs for installing into concrete use the correct size drill bit i use dewalts drill bits for stubborn concrete walls. the info for what drill bit you need is on the box and size of hole its 60mm deep so you want to make the hole 85mm 1 for imfections and 2 to allow a bit of the plastic to expand backwards as it make prevent the screw fitting snug. take everything into account one thickness of your bracket. lenghth of screw which is 80mm. measure your drill bit length put a bit of tape on the drill to the depth you want once you've hit your depth then put wall plug in. using a soft mallet i would advise camping one is fine made of rubber.
