Expansion anchor Fischer DUOPOWER 14 x 70 S LD

The Fischer DUOPOWER 14 x 70 S LD is a versatile expansion anchor designed for secure fixing in solid building materials such as concrete. The anchor combines two components — a grey nylon element and a red expansion wing — that interact automatically depending on the substrate to provide optimal function (expansion, folding or knotting) and reliable hold. The preshaped edge on the plug head prevents the plug from slipping into the drill hole. Screws delivered with the plug are optimally matched for correct insertion and tightening.

Advantages

The two-component design ensures very good holding values across a variety of base materials by activating the suitable function automatically. The red expansion wings support secure expansion and add safety to the grey nylon component. The anchor allows easy screwing-in and correct tightening without risk of over-tightening. The supplied screws are matched to the DUOPOWER anchor for consistent performance.

Suitable for

• Fixing heavy loads in concrete
• General construction and structural attachments
• Interior and exterior mounting where reliable mechanical anchoring is required

How to use

Drill a hole with a 14 mm drill bit to at least 100 mm depth, clean the hole from dust, insert the DUOPOWER plug until the preshaped edge rests on the surface, then insert the supplied screw and tighten. The plug’s components will activate according to the base material to create expansion, folding or knotting and achieve the required hold. Tighten until the plug seats; avoid excessive force once the anchor is engaged.

Usage recommendations

Use appropriate drill bits and personal protective equipment. Verify base material suitability before installation and follow relevant local building rules. For heavy or safety-critical loads consult product technical data sheets or a structural engineer to determine safe working loads.
