A stainless flat spring clamp for solar mounting hardware, holding cables, accessories and components onto rails and panel frames. Solar installations sit outdoors for decades and are effectively unserviceable once commissioned, which is what drives the material choice.
Solar hardware must outlast the maintenance budget. A plated clamp would be a failure point long before the panels are.
The clamp grips the rail or frame edge rather than requiring a drilled hole, which protects the frame's own coating.
Installation happens at height and often at speed. A clamp that fits by hand saves far more than its cost.
Confirm the clamp fits the rail across its manufacturing tolerance. Solar rails vary between production runs and a clamp fitted to a mid-tolerance sample may be loose on some deliveries.

Available in Stainless steel, Spring steel, Carbon steel, 65Mn, Music wire, in wire from 0.1-8 mm, with any of our nine surface finishing routes. Geometry, end treatment and finish are all specified per order.
ISO 9001, SGS certificate and RoHS report (stated on the legacy site, certificates pending re-confirmation). Certificate copies are sent on request once re-confirmed.
Against a cable tie, a stainless spring clamp does not embrittle in UV and does not need to be cut off to service the cable, at a much higher unit cost.
304 as standard. For coastal installations, discuss the grade with us before ordering.
Yes, and it should be. Send a section of the rail with your enquiry.
Tell us the cable type. Contact geometry can be formed to avoid a sharp bearing edge.
Send your drawing, dimensions or a sample. We will confirm the specification and come back with a price and a lead time.
