A difficult working position, bad lighting, strained muscles and drill dust in the face. Simply because of unfavourable working conditions, the overhead installation of suspended ceilings often results in substantial differences in the anchor setting performance, both in terms of quality and quantity. There is no need for that.
The fixing specialists at fischer have made the new FNA II Nail Anchor even easier to install and safer, with retaining values of 1.6 kN and a minimum anchoring depth of 25 mm. The European Technical Approval applies for the use of multiple fixings of non-load-bearing systems set in concrete, such as suspended ceilings, sub-constructions of ceiling linings or upright separating walls and conduits.
The benefits of the fischer FNA II Nail Anchor are particularly evident in series installation. The small drill hole diameter and the low anchoring depth save time and money during installation. Special drills, other tools or trial loads after the anchor installation are no longer required.
Anchor fixing is also made easier by low edge distances and axial spacings, and by smaller minimum building component thicknesses. In longitudinal decks beams, for instance, the fischer Nail Anchor can be set at 50 mm to the edge and with an axial spacing of 50 mm in the anchor cluster. The smaller minimum building component thickness of 8 cm also allows the installation of ribbed ceilings or narrow precast concrete units.
Drilling the hole, three blows of the hammer, and the FNA II sits tight – world-wide the first of its kind with European Technical Approval in ceilings of concrete class C12/15 (B15). The fischer FNA II Nail Anchor combines the working principle of a bolt anchor with the principle of hammerset installation, with no need to tighten the anchor after installation.
The fischer FNA II Nail Anchor is offered in zinc-plated steel, stainless steel grade A4 and highly corrosion-resistant steel grade 1.4592 in a variety of different head designs. The design variants with nail head, with metric thread, as hook and eyebolt allow a wide variety of different applications and uses.
