Rail-Free Mount Clamp for Metal / Tin Roof Solar Mounting Systems

Rail-Free Mount Clamp for Metal / Tin Roof Solar Mounting Systems

Product Description

Power Stone's Rail-Free Clamp redefines flexibility with its modular, no-drill design. Unlike generic clamps, it offers customizable base profiles to match unique tin roof corrugations. 

Engineered from aircraft-grade aluminum (6005-T5) and stainless steel (SUS304), these clamps eliminate rails entirely, slashing component counts and roof loads. Each rail-free mount clamp features a customized low-profile design with integrated EPDM rubber pads to prevent water infiltration and enhance grip, even in 150+ mph winds.

1. Lightning-Fast Installation
   • Single-tool, single-motion clamping—no rails, no measuring, no drilling—cuts on-roof labor by up to 50 %.
   • Pre-assembled cam lever and captive EPDM pad reduce parts count by 70 % and eliminate dropped hardware.
2. Zero-Penetration, Zero-Leak Design
   • Dual-layer EPDM gasket seals tightly around every tin rib, preserving the original roof warranty and eliminating leak paths.
   • Fully rail-free system means no through-roof bolts, rivets, or sealants—ever.
3. Hurricane & Snow Certified
   • Independently tested to TAS-100 (a) and IEC 62817: 170 mph (75 m/s) wind and 1.6 kN/m² snow load.
   • Marine-grade 304/316 stainless hardware delivers 25-year corrosion resistance—even in coastal salt-spray zones.
4. Ultra-Low Visual Impact
   • Rail-free architecture keeps array height at just 22 mm above the roofline for a sleek, “floating” appearance that meets HOA aesthetic rules.
   • Black anodized finish blends seamlessly with dark modules, minimizing glare and wildlife intrusion.
5. Built-In Grounding & Cable Management
   • Integrated grounding rivet creates continuous electrical bond across the array—no separate lugs, straps, or jumpers required.
   • Side-entry wire-keeper slot secures PV wires and optimizers, maintaining a clean underside profile.
6. Freight & Storage Savings
   • 50 kW of hardware ships in two 38-lb (17 kg) cartons—60 % lighter and 75 % smaller than traditional rail systems—slashing freight costs and on-site storage needs.
