No - Generally ‘hanger bolts’ do not have a technical approval!
The good news – ‘The EJOT Solar Fastening System is NOT a hanger bolt!’
A hanger bolt and the EJOT Solar Fastening Systems are looking very similar. In fact this is the reason why these products are often being confused with each other.
Decisive is that the design of the EJOT Solar Fastening Systems differs from the hanger bolt with some fundamental characteristics. In fact this is the reason why the EJOT Solar Fastening System is the first fastening system for solar installations that was technically approved by building authorities in Germany.
The translation of German Technical Approval of the EJOT Solar Fastening Systems JA3 & JZ3 (Z-14.4- 532) can be downloaded in the download section, as well as the respective technical data sheets.
