fischer DuoHM 6x55 S PH PZ Taco para huecos 55 mm, 25 uds. 572922

Mounting fixtures to hollow or panel walls often ends in frustration: standard plugs spin, pull out, or crush the board. The fischer DuoHM 6x55 S is a hollow wall anchor that grips firmly in plasterboard, gypsum fibreboard, and other cavity panels, giving you a reliable fixing point for shelves, cabinets, and light fixtures. Its zinc-plated steel construction resists corrosion, while the 55 mm length and 6 mm diameter suit panels from 10 to 20 mm thick. The pre-positioned installation method lets you set the anchor through the fixture, then drive a wood or chipboard screw (4.0–5.0 mm) with a Phillips or PoziDriv bit. Each pack includes 25 anchors, enough for multiple projects.

Who is it for

Electricians, carpenters, and DIYers who need secure fixings in hollow walls without access to the cavity. Ideal for mounting lightweight fixtures, cable trays, or brackets in drywall, hollow brick, or light building boards.

Tips

Drill a 6 mm hole at least 65 mm deep. Insert the anchor through the fixture and into the hole, then drive the screw until the anchor expands behind the panel. For best results, use a screw length that accounts for fixture thickness plus anchor length. Avoid over-tightening to prevent crushing the board.
