Solar Mounting Hardware

Solar mounting hardware is the structural layer that holds a photovoltaic array to a roof, pole or ground bed for the twenty-five year life of the system. Urban Supply carries rails, mid and end clamps, L-feet, flashings, splices, grounding lugs and complete pole and ground mount kits from the manufacturers installers specify by name.

How to Choose

Start with the roof or mounting surface, not the panel. Asphalt shingle takes a flashed L-foot; standing seam metal takes a clamp that never penetrates the roof; corrugated metal needs a bracket matched to the rib profile; tile requires a hook or a no-penetration ballast base. Once the attachment is settled, size the rail to your module dimensions and local wind and snow loads, then confirm the clamp fits your module frame height — most fall between 30mm and 40mm.

Key Specifications Explained

  • Attachment type: Flashed L-foot, standing-seam clamp, rib bracket, tile hook or ballast base
  • Rail length: Commonly 84 inch (7 ft) and 168 inch (14 ft) sections, spliced for longer runs
  • Clamp range: Match to module frame height, typically 30-40mm
  • Grounding: Bonded splices and grounding lugs maintain electrical continuity across the array
  • Finish: Mill or black anodized — black disappears against dark modules

Brands We Carry

We stock IronRidge, SnapNrack, Pegasus Solar, Tamarack Solar, S5!, Top Rack Technology, IntegraRack, Rescom, DynoRaxx and PowerField — covering roof, ground, pole and carport mounting.

Frequently Asked Questions

Do I need a grounding lug on every rail?

Bonded splices maintain continuity along a rail run, so most arrays need one lug per continuous rail rather than one per section. Follow the manufacturer's instructions and your local inspector.

Can I mix rail and clamps from different brands?

Do not. Clamp geometry, rail channel profile and bonding are engineered together, and mixing voids the structural warranty and the UL 2703 listing.

What about standing seam metal roofs?

Use a seam clamp such as the S5! range. It attaches without penetrating the roof, so the roof warranty stays intact.
