For easy installation of electrical equipment, electrics or switch boxes on insulated ceilings and walls, minimum installation depth in the load-bearing substrate = 45 mm, drilling diameter = 10 mm, minimum drilling depth = total length DHI + 10 mm - insulation thickness. The 50 mm dowel part must find a hold in a solid substrate, screw in straight, correct screw size and no forceful processing. Recommended screws: sheet metal or chipboard screws 4 mm diameter, screw-in depth in DHI = 10-15 mm, easy insertion with thumb pressure, no cold bridge, infinitely variable installation depth, light gray, halogen-free PA 6, UV-stabilized, temperature range: -20 degrees C to +85 degrees C, silicone-free, insulation thickness 6-8 cm
