Expansion anchor Fischer DUOPOWER 8 x 40 S LD

The Fischer DUOPOWER 8 x 40 S LD is a versatile expansion anchor designed to provide secure fastening in a range of base materials. The plug combines two components — a grey nylon part that automatically activates the appropriate function for the substrate (expansion, folding or knotting) and a red part with expansion wings that enhances anchoring security. The preformed edge on the plug head prevents the anchor from slipping into the drill hole. Screws supplied with the plug are matched to the DUOPOWER design for reliable installation.

Advantages

The two-component design delivers very good holding values by selecting the correct mechanical action for the building material. Expansion wings on the red component add extra support to the grey nylon element. The plug head’s preshaped edge ensures correct positioning in the drill hole and helps avoid over-tightening when the screw is driven. Included screws are optimally suited to the DUOPOWER anchor.

Suitable for

• Concrete
• Solid masonry
• Hollow and perforated bricks (uses folding or knotting action)
