## Description

From the manufacturer fischer DuoPower Plug The fischer DuoPower offers very good hold values as a result of its 2 components: Depending on the building material, the grey components made from high quality nylon automatically activates the optimum product function (expansion, folding, knotting) for the best hold. The expansion wings of the red component support the secure expansion and offer additional security to the grey component. Easy turning-in of the woodscrew and correct "tightening" to close. No over-tightening of the woodscrew. The preshaped edge on the plug head prevents the plug from slipping into the drill hole. Building materials Concrete Solid brick Solid sand-lime brick Aerated concrete Vertically perforated brick Perforated sand-lime brick Plasterboard Gypsum plasterboard and gypsum fibreboards Hollow blocks made from lightweight concrete Chipboard Advantages - Two component materials for top load values and intelligent functioning depending on the substrate. - Great feedback (feel-good factor) of the plug. You can feel exactly when the plug is installed perfectly. - The narrow plug rim prevents slipping into the drill hole. - The serrated anti-rotation feature prevents rotation in the drill hole during installation.

## Questions & Answers

**Q: What is the weight capacity of these plugs ?**
A: I used these plugs on a mirror weighing in excess of 20kilos, 2 plugs at 400mm apart, but the wall was really solid though.they are also holding up kitchen cabinets. In a solid wall it's a great anchor. 
Note: try not to use hammer drilling to do thé holes for the plugs. If you get a drill bit that can do masonry holes without the hammer action it holes way better, if not, use a drill bit 1mm smaller. 
Once that screw goes in, it takes a lot to come out.

**Q: are these suitable for plasterboard cavity wall**
A: Depends on what you need to mount on the wall and the space between the plasterboard and the wall/ studwork the plasterboard is affixed to. I use these for fairly heavy items (large mirrors) on my wall that consists of plasterboard fixed with dot and dab to the wall behind, So with a 15mm board and a 15 to 20mm gap to the wall these are ideal. For lightweight items with a hollow behind the plasterboard use the shorter Duopower. For heavy items on plasterboard with a hollow behind I use the two part metal cavity fixings that use have m4 or m5 threads.

**Q: What would be the best screws to use ? ty**
A: It doesn't matter too much. Any regular zinc plated single thread screw will work, including wood screws, self tapping screws or coach screws. It's the size you need to pay attention to, I believe you need either 4mm or 5mm screws. The length would be the "plug length + fixture thickness + 1x the screw diameter", ie 55mm + fixture thickness.

**Q: Are these the right size for 6mm x 50mm coach screws? It's confusing - not sure if you match the size to size of screws or if it is different.**
A: The 6mm x 50mm refers to the drill hole size. 
I would recommend a 8mm drill hole for a 6mm screw. Fischer do a 8mm x 50/60mm duopwer plug.
Hope this helps.
