Description
Dromet PSRe M20×270/123 galvanised ring shell anchor
The PSRe 20×270/123 ring anchor by Dromet is a proven expansion fastener designed for permanent fixing of structures in non-cracked concrete. Thanks to its ring-shell design, it provides high load capacity and secure anchoring — an ideal choice for installing solar PV mounting profiles, steel structures, grating platforms, handrails, machinery and equipment in industrial facilities.
The fastener holds a European Technical Approval ETA 05/0242, a CE certificate, and is covered by national approval AT-15-7574/2008, confirming compliance with strict safety requirements and permitting its use in load-bearing structures.

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 with light hammer taps. Installation should be carried out using a torque wrench — after the anchor has expanded, the washer under the nut should be firmly pressed against the fixed element. All load parameters and installation distances are specified in Technical Approval AT-15-7574/2008 — exceeding them is not permitted.
