Suitable for heavy duty fixing applications such as radiators and wall units. Anti-rotation teeth pierce the base skin to ensure film anchorage. Screw and fixing can be removed. Specialist fixing gun can be used for repetitive fixing applications. Suitable for use in most types of hollow walls, fibreboard, plasterboard and partitions. These Forgefix Cavity Wall Anchors are a specialist plasterboard fixing with Pozi and slotted combination drive insert. They have an all-metal construction for applications which require heat resistance and are Zinc Plated for increased resistance to corrosion. The anchors have anti-rotation teeth, which pierce the base plasterboard skin to ensure firm anchorage. All metal construction means the anchors are suitable for the heavier duty tasks such as fixing radiators and wall units. Zinc coatings prevent oxidation of the protected metal to create a longer lasting finish. It does this by forming a barrier and by acting as a sacrificial anode if this barrier is damaged. Zinc oxide is a fine white dust that (in contrast to iron oxide) does not trigger a breakdown of the substrate's surface.
