## Description

Fischer 544546 Duopower Universal Dowels Kit with Screw, Transparent" Fischer Duopower KIT DUOPOWER 80 Dowels Case with Screw (160 Pieces total) Advantages: Two components for higher load values and intelligent operation (expansion, bending, knotting) depending on the support material. The best possible feedback in tightening. It is possible to feel with certainty when the fastening is installed perfectly. The small length of the fastening ensures quick installation without deep drilling. Thin fastening collar prevents slipping into the hole. Close anti-rotation fins prevent rotation in the hole during installation. Support materials: Concrete Solid brick Full Calcium Silicate Brick Full lightweight concrete block Semi-solid brick (vertically perforated) in brick Semi-solid brick (vertically perforated) made of calcium silicate Lightened Concrete Cable Block Autoclaved aerated concrete (aerated concrete) Plasterboard Plasterboard sheets and gypsum fiber boards Concrete and brick hollow slabs or similar Natural stone Particle board Full plaster panel Applications: TV shelves Lighting Shelves Mirror Cabinets Letter Boxes Paintings Roller blinds Curtain rails Fixings for washbasins Hydraulic and heating fittings Accessories for bathrooms Hanging furniture Cooker hood Operation: The DUOPOWER is suitable for pass-through and non-through installation. The coupling of two different materials and its multiple functional abilities (expansion, bending and knitting) extend the range of applications to additional materials with high loads. The required length of the screw is provided by the length of the dowel + the thickness of the object to be fixed + 1 x diameter of the screw Suitable for wood and chipboard screws as well as for double threaded screws. In the case of fixing on panels, the unthreaded part of the screw should not be longer than the object to be fixed. The distance from the edge must be at least once the length of the fastening.

Review: easy and simple to use - Needed some new drill bits, these are quite good as they have 4 pointed head than the standard 2 which makes it easier to drill holes required. Have used loads of different wall plugs but hands down FISCHER is the Best as they multi-purpose.
Review: Mr jay Williams - Recently I had some building work done in the house. The builder recommended these drillbits and the wall plugs and screws. Yes definitely recommend them 10 out of 10.
