Sunmodo MRB | Metal Roof Mounting Attachment (Rail-Less System)

MRB™ Rail‑Less Metal Roof Attachment – Universal Fit, Record‑Fast Installs

Engineered for corrugated, R‑panel, and standing‑seam profiles, SunModo’s MRB™ is the most adaptable rail‑less solar mounting attachment for metal roofs. The low‑profile bracket ships fully pre‑assembled with an integrated EPDM gasket, delivering a watertight seal the moment it’s fastened to sheet metal or wood decking—no extra sealant, no loose parts, no wasted minutes.

Pair MRB™ with SunModo’s SMR™ rail‑free system and finish rooftops up to 40 % faster, slashing labor costs while maximizing array density and curb appeal.

• Most versatile metal‑roof attachment — one SKU fits corrugated, R‑panel, and standing‑seam roofs for streamlined inventory management.
• Precision‑adjustable design lets crews quickly align modules and hit code‑required standoff heights without re‑drilling.
• Factory‑installed adhesive gasket guarantees instant, leak‑free sealing and preserves roof warranties.
• Rapid anchoring to metal sheeting or decking cuts install times and eliminates specialized tools.
• HVHZ certified & TAS 100(a) wind‑driven rain tested — proven durability in hurricane‑prone zones.
• Rail‑less compatibility with SunModo SMR™ and other leading rail‑free platforms reduces material costs and visual profile.

Choose MRB™ for your next metal‑roof project and experience the fastest, most flexible rail‑less attachment—built to meet strict design loads, withstand extreme weather, and keep installers profitable.
