## Description

Product description Product Highlights DUOPOWER Short length allows fast install with shorter screws Soft & hard components enable optimal screw-in & tightening torque Red expansion wings support safe spreading & additional safety to the nylon base High-quality nylon body automatically activates for secure fastening Narrow edge prevents slipping DUOPOWER: Intelligent self-activating functioning depending on the substrate. For a wide range of applications. DUOPOWER: The duo of power and intelligence. Simply clever, the combination of two components for better performance. Functional Zone I: Aerated Concrete The dowel point spreads in two directions for higher pull-out forces in problematic building materials. Functional Zone II: Hollow Building Materials The spreading element spreads at a 90° angle to zones I and III and ensures optimum screw guidance. Functional Zone III: Drywall/Plasterboard The rear area of the anchor folds or spreads, depending on the building material. DuoPower: Easy installation and optimal performance.

Review: Exceptional Load Transfer & Unparalleled Convenience - The DuoPower has rapidly become my go-to solution for all sorts of anchoring needs. What sets this product apart is its intelligent function: it's the first plug I've seen that adapts to the material it's being used on. Whether it's solid, perforated, or panel building materials, the DuoPower smartly adjusts to transfer high loads through folding, expanding, and knotting. In my experience, this plug is truly an all-in-one solution for a wide variety of building materials. The ingenuity of the 2-component plug lies in the grey component that automatically activates the optimal operating principle based on the material, while the red component's expansion wings ensure safe spreading. What impressed me further was its strength. Despite being compact and short, the DuoPower requires noticeably less drilling effort and shorter screws. It's thoughtfully designed to prevent slipping into the borehole, resist rotation within the drillhole, and offer tactile feedback when perfectly installed. The DuoPower anchors have proven to be incredibly versatile, working well for attaching everything from shower curtain rails to mailboxes, lamps, motion sensors, and signs in a variety of materials such as concrete, bricks, natural stone, gypsum plasterboard, fibreboard, and chipboard. From my perspective, these are the best drywall and multipurpose anchors on the market. They provide an excellent grip and are incredibly straightforward to install. I couldn't recommend them more."
Review: Perfect replacement for cheap drywall anchors - Notable occurrence: since installing these, we had a 3.5 magnitude earthquake (epicenter ~1 mile from my house) and 2.5 aftershock. The guitar collection is still hanging up just fine. I recently purchased a wall-mount guitar hanging system. The rail-based system with movable guitar hangers was just what I needed to get a good chunk of my collection off the floor and nicely displayed. BUT the included wall hangers were utterly sub-par. Half of them were barely gripping the screw and even once a screw was fully inserted, they could be pulled right out of the drywall--hardly what I want with 16 guitars. And because the system is a long wall-mounted rail with evenly spaced holes, I didn't have the option of ensuring that I could hit multiple studs. and needed the drywall anchors to be pitching in. After looking through quite a few products I stumbled upon these. Rather than giving up on the system entirely, I simply tossed all of the anchors that came with it and replaced with these. It's now easily holding 16 guitars and feels like it would be able to hold twice as many (although I'm not going to try). No, this isn't the most exciting product out there. But if you're going to hang something up and rely on drywall anchors, it makes sense to use ones that will work. These do the job perfectly, and are notably better than the anchors they were replacing, so I have to give them 5-stars.

## Features

- Combination of two material components for more performance.
- Secure functions for solid (expansion) and hollow and panel building materials (folding/knotting).
- Easy installation: narrow edge of the plug prevents it from falling deeper into the drill hole.
- Best possible feedback from the anchor - you can feel that the anchor is sitting perfectly.

## Questions & Answers

**Q: How pounds is this anchor rated for?**
A: Hi! Thanks for your question. Up to 55lb per single plug.

**Q: Will these work on thin paneling such as hollow doors or RV walls?**
A: I’m not sure. They are pretty deep (over 1 inch)  and not sure if they would compress enough to hold securely on thin panel. For that purpose I would use another style mollie that is made to compress with greater rear support.

**Q: Are the screws stainless or zinc coated?**
A: Stainless steel

**Q: Can these be used with # 6 screws?**
A: Hello, thanks for the question. 
#6 screw would run small for the 5/16", we recommend #8-#12 for this plug size.

### ⭐⭐⭐⭐⭐ Another Wall Anchor
*by S***R on November 19, 2024*

There are many types of wall anchors. Some like "Molly bolts" and "Toggle bolts" are quite secure in hollow walls, but useless in solid walls. Some like "Tapcon", "RedHead, and "Strike Anchors" only work in solid walls. These DuoPower plug anchors are light weight anchors that will function in both solid or hollow walls. The manufacturer says they adapt to almost any material, or material thickness. They are a great improvement over plastic anchors. I have occasionally had various problems over the years with nearly all anchor types. The Fischer DouPower anchors have so far, been very well behaved. Consult the instructions for the best results. You will also need the correct size drill bit, designed for the material you are installing the anchors into.
