Description
Dromet PSRe M20x220/73 ring expansion anchor, electro-galvanised
The PSRe 20×220/73 ring anchor manufactured by Dromet is a proven mechanical fastener with a ring-type design, intended for the permanent fixing of profiles, metal structures, gratings, railings, machinery and other equipment of building structures. The anchor is supplied complete with a nut and washer, ready for immediate installation — which helps shorten the working time of the site crew.
The fastener is designed for substrates made of non-cracked concrete min. class B20, natural stone with a dense structure and solid brick. It holds a European Technical Approval ETA 05/0242, a CE certificate and a national approval AT-15-7574/2008, confirming full compliance with regulatory requirements and simplifying acceptance procedures for the works.

Installation recommendations
The mounting hole must be drilled perpendicular to the substrate surface and thoroughly cleaned of drilling dust. The fastener should be able to be inserted into the hole with light hammer taps. Installation requires the use of a torque wrench — after the anchor has expanded, the washer under the nut must be firmly tightened 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 — both for mounting photovoltaic structures on concrete substrates and for fixing heavy equipment components in industrial and public-use buildings.
