Certified stainless-steel end and mid clamps secure 30 to 50 mm frames and lock to anodised rails with a single Torx drive, slashing installation time. Integrated serrations pierce anodisation, guaranteeing ≤ 0.1 Ω bonding resistance and creating a continuous protective earth path across the array. Earthing plates couple rows without copper lugs, and double-threaded bolts permit adjustment after initial placement. All hardware passes static tests for snow loads above 5.4 kN m2 and wind uplift to 44 m s, meeting Eurocode and local Latvian standards. Stock arrives boxed in 100-piece sets with QR codes linking to MCS/TÜV certificates for compliance documentation on-site.
