The Fischer DuoPower is an intelligent 2-component universal plug that automatically adjusts to the substrate for optimal load transfer. It features three functions: folding, expanding, and knotting, making it suitable for a wide range of applications in solid, perforated, and panel building materials. The compact and short design requires less drilling effort and shorter screws. Its narrow rim prevents slipping into the borehole, and the anti-rotation feature stops it from turning. The included screws are perfectly matched to the plugs. Ideal for attaching shelves, cabinets, curtain rails, and more to concrete, bricks, stone, gypsum plasterboard, and fibreboard. Includes 50 DuoPower 8 x 40 S PH LD plugs and 50 panhead screws 5 x 60.
