Expansion anchor Fischer DUOPOWER 14 x 70

The Fischer DUOPOWER 14 x 70 expansion anchor combines two components to provide reliable fixing performance in a range of base materials. The grey nylon part automatically activates the appropriate function—expansion, folding or knotting—depending on the substrate to deliver secure anchoring, while the red expansion wings support and stabilise the expansion process. The preshaped edge on the plug head prevents the anchor from slipping into the drill hole and allows correct positioning before screwing.

Advantages

The two-component design yields consistently good load values across different building materials. The grey high-quality nylon element adapts its function to the substrate, and the red expansion wings add extra security during expansion. The anchor allows easy screwing in and achieves reliable closure without risk of over-tightening the screw, ensuring repeatable and durable fixes.

Suitable for

• Concrete and solid masonry
• Hollow or perforated blocks where folding or knotting is required
• General mechanical and structural fixings indoors and outdoors
• Installations requiring 14 mm drill diameter and 70 mm anchor length

How to use

Drill a hole with 14 mm diameter to at least 80 mm depth, clean the hole from dust, and insert the DUOPOWER anchor so the preshaped head sits flush. Place the fixture over the anchor and insert the correct screw. Tighten the screw until the anchor has expanded, folded or knotted as appropriate for the substrate; the design prevents over-tightening. Ensure the fixture is held in the desired position while tightening.

Usage recommendations

Use the Fischer DUOPOWER 14 x 70 for load-bearing fixings in concrete and appropriate masonry; select screw length according to fixture thickness and follow drill depth and diameter recommendations for optimal performance.
