Drop-in anchor for secondary attachments on porous surfaces, e.g. pumice, lightweight or aerated concrete. Zinc-plated steel

Can be used in various base materials such as PB2/PB4 autoclaved aerated concrete, perforated brick, pumice or lightweight concrete.

The fixing is driven in until flush without pre-drilling in PB2 autoclaved aerated concrete.

The W-MG 8 metal fixing, in conjunction with the M8 hanger bolt, conforms to the requirements of the TRGI (German Technical Guidelines for Gas Installations). Item 3.3.7.2 of these guidelines stipulates the requirements for laying the inner pipes: "Pipe fasteners must be fire resistant. The supporting parts of pipe fasteners must be made of non-flammable materials."

Proof of Performance

Fire resistance: F30, F60, F90 and F120 (anchoring base: ≥ Vertically perforated brick HLZ 12, hollow sand-lime brick ≥ KSL 12, ≥ aerated concrete, strength class 4)

Exposure to fire according to DIN 4102-2:1977-09 (uniform temperature time curve)
