System Components
To build a fully functional SM ASCENDER® system, the following components are required:

Wire Mgmt Clips
Unirac offers a full range of Heyco SunRunner® clips for clean, secure cable management across solar installations. Designed to fit a wide variety of extruded aluminum profiles, these clips route cables neatly along module frames or mounting channels. Smooth edges protect cable insulation, while locking tabs ensure a firm hold. Each clip features a screwdriver slot for easy repositioning during or after installation.

Grounding & Bonding
Unirac offers trusted solutions for system grounding using the WEEB® Lug or ILSCO lay-in lug. Each features dimpled washers that pierce the rail’s anodized coating to establish a secure electrical bond. A solid copper wire connects to the lug and is routed to deliver a dependable final ground connection—ensuring safety, code compliance, and long-term system performance.
