DuoPower 1/4" x 1-3/16", Powerful Universal Plug with Intelligent 2-Component Technology for fastenings in Concrete, Bricks, Gypsum plasterboard, chipboard, etc., 100 Plugs Without Screws

Now I only need to carry around this one wall plug in order to mount screws into a variety of wall types, replacing several others. And it has better grip than most!

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."

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.

The anchors are great! 5 stars for that. Packaging was a mess! They came in two small boxes labeled as 100 in each box that was also packaged with some shirts in a bag. When I checked to see how many there were, there were about 50 missing (I ordered 2 boxes of 100 and there were only around 150 that made it). They probably fell out through the hole in the bag. 1 star to Amazon fulfillment for poor choice of packaging.

This is a fantastic product. They work extremely well and versatile in a range of wall materials. If you see any reviews about them "falling out of the wall" that person clearly hasn't followed instructions on how to use them. I unfortunately am giving the product 3 stars since the Amazon fulfillment center can't figure out how to send me the right product. I've ordered boxes of (100) 1/4" duo-power anchors multiple times now and they keep sending me 50 anchors with 50 screws. Fischer, you might want to look into this. They keep F-ing up your orders. The boxes of 100 anchors and boxes of 50 pairs seem to have the same UPC code, unless one of them is incorrectly boxed. It's happened four times now. I love your products. If I could only get my hands on the right ones.
