The Knauf metal cavity plug DN 6x40 is a high-quality fastening solution engineered specifically for secure installations in hollow wall structures and plasterboard. Constructed from durable metal, this anchor provides exceptional stability and load-bearing capacity, making it an essential component for professional interior finishing and renovation tasks. Its design ensures a firm grip behind the panel, preventing rotation and ensuring long-term reliability in thin-walled building materials.
Advantages
This metal cavity plug offers superior strength compared to standard plastic alternatives, ensuring that heavy fixtures remain securely attached to plasterboard surfaces. The robust metal construction resists deformation under load, providing peace of mind for both residential and commercial applications. Its specialized geometry allows for easy installation while maintaining a high level of pull-out resistance, which is critical for safety and structural integrity in hollow wall systems.
Suitable for
- Mounting shelves and cabinets on plasterboard walls
- Installing wall-mounted lighting fixtures
- Attaching decorative elements to hollow partitions
- Securing bathroom accessories in drywall constructions
This product is not suitable for use in solid masonry, concrete, or brick walls, as it is specifically designed to expand behind thin panels. It should also not be used for heavy-duty structural loads that exceed the weight capacity of the plasterboard itself.
Key specifications
- Material: Metal
- Length: 40 mm
- Diameter: 6 mm
- Color: Silver
- Quantity: 100 pieces
How to use
To install the Knauf metal cavity plug, first drill a hole in the plasterboard with a diameter matching the plug size. Insert the plug into the hole until the collar sits flush against the surface. Use a compatible screw to expand the metal wings behind the board, ensuring the fastener is tightened until it is firmly locked in place. Once the anchor is expanded, you can mount your desired fixture securely.
What to consider before purchase
- Verify the thickness of your plasterboard to ensure compatibility with the 40 mm length.
- Check the total weight of the object to be mounted to ensure it falls within the safe load limits for drywall.
- Ensure you have the correct drill bit size for a 6 mm diameter installation.
Usage recommendations
For optimal performance, always ensure the plug is fully expanded behind the wall panel before applying the final load. Avoid over-tightening the screw to prevent damage to the plasterboard surface.
