Description

The Renusol Solar Fastener for Steel Substructure (Part No: REN-900183, 125/50) is a pre-assembled clamping fastener designed to secure solar PV mounting equipment directly to steel purlins and steel substructures, without the need for drilling into the steelwork. Manufactured entirely from stainless steel, the fastener clamps around the steel section using a hexagon socket setscrew.

With a clamping range of 60.0–105.0mm, this 125/50 variant suits mid-range steel purlin depths, and carries full MCS, TÜV, and DIBt building approval for use in certified UK solar PV installations.
