Installation recommendations
The mounting hole should be drilled perpendicular to the substrate surface and thoroughly cleaned of drilling dust. The fastener should be able to be inserted into the hole using light hammer taps. Installation requires the use of a torque wrench — after the anchor has expanded, the washer under the nut must be firmly pressed against the fixed element. The parameters specified in approval AT-15-7574/2008 must not be exceeded.
The Dromet PSRe ring anchor is a reliable choice for professional installation crews — whether for mounting photovoltaic structures on concrete substrates or for fixing heavy equipment components in industrial and public buildings.
