HellermannTyton Solar Locking Clamps are ideal for fastening wire and cable bundles to panels. The HellermannTyton Solar Locking Clamps feature a uniquely engineered fir tree that holds tightly in pre-stamped holes. The locking clamp mechanism dynamically fits various bundle sizes, while an integrated cable tie saddle option on the 9mm x 12mm version allows installers to add additional cable runs. The Solar Locking Clamp with Edge Clip provides a universal design that can fit on a wide variety of edges without using a cable tie. HellermannTyton Solar Locking Clamps are designed for solar panel frames and racking edges.
