The fischer duotec 12 toggle plugs deliver engineered precision for professional installation across hollow and solid building materials. Designed for pre-positioned installation, these toggle plugs prevent fall-through even without screws, while requiring only minimal drill hole diameters for efficient, time-saving deployment. The innovative toggle element automatically folds behind panels, distributing load without compromising the structural integrity of gypsum plasterboard. The flush sleeve strengthens drill holes and accommodates higher transverse loads, while the soft grey nylon contact surface minimises material weakening. The flexible stainless steel screw seat provides exceptional compatibility with wood screws, chipboard screws, metric hooks, and threaded rods with lock nuts. When encountering solid materials such as concrete or wood, the plug functions as an expansion anchor, ensuring reliable performance across diverse installation conditions. Features & benefits: suitable for kitchen cupboards, shelves, wardrobes, handrails, pictures, mirrors, lamps and heavy hanging baskets. Compatible with gypsum plasterboard, fibreboard, wooden panels osb, chipboard, mdf , steel plates, plastic boards, and hollow concrete blocks. Glass fibre-reinforced plastics and metal skeleton insert for heavy tensile and transverse loads. Scale on grip strap for determining required screw length scale value 20mm .
