Review: Fantastic rawlplugs. - These Fischer Duopower rawlplugs (wall plugs) are absolutely fantastic. Like most of us, I've been using the standard yellow/red/brown rawlplugs, that haven't really changed in 50 years. When you open the box of these, you know they are something different. The manufacturing quality is plain to see. They are made in Germany and they ooze class. On the side of each plug is written the word Duo, followed by the diameter of the drill needed, and the diameter of suitable screws. This information is also on the box (Photo 1). The 8mm diameter ones are for use with screws 4.5-6mm diameter. The 6mm diameter ones are for use with screws 4-5mm diameter. (The length of screw is dependent on which plugs you buy, but the screw can be longer than the plug. Just make sure you drill a deep enough hole.) I have used 4mm screws with the 8mm plugs and they feel good and strong to me, however, it is advisable to follow the manufacturers instructions to be able to achieve the full load bearing numbers. They are lovely in use. Easy to insert, either push fit, or with a light tap, and once screwed in, nigh on impossible to pull out. The way they work is very clever, deforming themselves in 3 different ways, depending on the substrate you're using. All of the clever science is in the listing above. (The only place I personally wouldn't use them is screwing into plasterboard. I'm sure they would work well, but I'm a big fan of JCP Blue Rosettes.) Update: I have now tried them on plasterboard and they work well, however, I have found, that due to the crumbly nature of plasterboard, if you use a drill size 1mm smaller than stated, then they hold incredibly firmly.) They are more expensive than standard plugs, but not that much and believe me, the extra is worth every penny. I cannot ever imagine going back to 'ordinary' rawlplugs ever again. Strongly recommended. I hope you found this review helpful.
Review: Premium product - I use these Fischer plugs at home for domestic use. I'm not expert when it comes to DIY, but the look and feel of these plugs compared to other brands fills me with confidence. They come across as a premium, superior product. They are the only brand I'll use in the home when putting anything on the walls. Haven't had any issues so far. Extremely sturdy and easy to install. Would definitely recommend.

A: These are probably best plasterboard anchors on the market certainly best I’ve used but to be honest if this is a heavy unit I’d probably cut a couple of holes out the plasterboard and set 2 lengths of wood behind the plasterboard and screw into these.

### ⭐⭐⭐⭐⭐ Top notch quality product
*by R***M on 27 July 2024*

Its is a top notch quality product, crisp and precise images on the box for using the correct masonry drill bit for it to sit perfectly in the hole. Securely held with the mortar and does not rotate when fixing the screw or unscrewing. Easy to fit / remove panels without causing any damage to the wall plastering. Can be trimmed in size and still used effectively if you accidentally happen to fall short a wee bit while drilling due to a reinforced/ribbed bar in the concrete wall while drilling.
