Mixed set of Fischer Duopower nylon wall plugs in a stackable, refillable Fixtainer box. Includes 120 x 6mm, 60 x 8mm and 30 x 10mm plugs. Works in solid and hollow walls, up to 15kg load capacity per fixing.
The Fischer Duopower Plugs Fixtainer is a mixed selection of one of the most reliable universal wall plugs on the market, packaged in a sturdy, stackable storage box that actually earns its place on the shelf. Three sizes in one box: 120 x 6mm, 60 x 8mm and 30 x 10mm. Whether you are chasing a job through solid concrete, plasterboard, hollow block or perforated brick, the Duopower adapts to the substrate without you having to switch plug types. That alone saves time and reduces the number of boxes rattling around in the van.
The plug is made from a two-component nylon material. The harder outer nylon expands reliably in solid masonry, while the softer inner section folds or knots behind hollow materials to create a secure mechanical fix. It is a straightforward principle and it works well across a wide range of substrates. Load capacity reaches up to 15kg per fixing, which covers most everyday installation tasks comfortably.
What Makes the Fischer Duopower Worth Carrying
A few design details stand out in practice. The narrow plug rim sits flush rather than riding proud of the surface, which matters when you are doing a push-through installation or positioning a bracket. The serrated outer profile grips the drill hole and stops the plug spinning when you drive the screw, which is one of those small things that saves a surprising amount of frustration. Plug length is kept short deliberately, so you are not drilling deeper holes than necessary. There is also a tactile feedback mechanism built in so you can feel when the plug has seated correctly. Useful when you are working overhead or in a tight corner and cannot easily see what you are doing.
The Fixtainer box stacks with other Fischer Fixtainer boxes, which keeps a cluttered site box or van shelf a little more organised. It is refillable too, so once the plugs are gone you are not throwing the box away. For anyone who goes through Duopower plugs regularly, the fischer duopower plugs fixtainer format makes a lot more sense than loose bags.
Pro Tip: In plasterboard, always use the 8mm or 10mm Duopower rather than reaching for the 6mm, the larger diameter gives a much better knot behind the board and holds firmer under load.
Fischer Duopower plugs are used daily by electricians, plumbers, joiners, and general builders fixing into a wide range of wall and ceiling substrates. They suit fixing battens, skirting, architrave, pipe clips, cable management, socket back boxes, radiator brackets, mirrors, shelving and light fittings. Because the plug works in both solid and hollow construction, it is the one you can reach for without overthinking which wall type you are dealing with, which is useful on a refurb where wall construction varies room to room.

Stackable refillable Fixtainer box
Not suitable for: Not suitable as a structural fixing or where loads exceed the rated 15kg per plug. Not recommended for damp or permanently wet environments without checking corrosion resistance of the screw used alongside.
Mark and drill your hole to the correct diameter for the plug size: 6mm plug needs a 6mm bit, 8mm needs 8mm, and so on. Keep the drill perpendicular to the surface and clear the dust from the hole before inserting the plug. Push the plug flush to the wall surface, you will feel it seat when it is in correctly.
Drive the appropriate screw into the plug steadily. In solid masonry the plug expands outward. In hollow materials it will fold or knot behind the wall, which you will feel as slight resistance increasing as the screw tightens. Do not over-drive, snug is sufficient.
Select the correct plug size for your screw and load requirements
Drill to the matching diameter, keeping the bit square to the surface
Clear dust and debris from the hole before inserting the plug
Push the Duopower plug into the hole until it sits flush with the surface
Position your fixing or use push-through installation as required
Drive the screw steadily until firm resistance is felt and the fixing is secure
Do not overtighten, particularly in plasterboard or hollow block
Can I use the Fischer Duopower in plasterboard without a separate plasterboard fixing?
Yes. The Duopower is designed to work in hollow walls including plasterboard. As the screw is driven in, the softer inner nylon folds or knots behind the board to create a mechanical anchor. Use the 8mm or 10mm size for the best result in plasterboard, as the larger diameter gives more material to work with behind the board.
What sizes are included in the Fischer Duopower Fixtainer and how many plugs in total?
The Fixtainer contains 210 plugs across three sizes: 120 x 6mm, 60 x 8mm and 30 x 10mm. The box is stackable and refillable, so it is worth holding onto once the plugs are used up.
Fischer Duopower plugs are manufactured from a dual-component nylon formulation. The harder outer shell provides reliable expansion in dense substrates, while the softer core deforms to anchor the plug in hollow or low-density materials. Rated to 15kg per fixing under typical installation conditions, the design meets the demands of everyday light to medium-duty fixing tasks across a broad range of building substrates.
