Rail-less racking for Trapezoidal metal roofs

R-panel, trapezoidal metal



Fast-Installing Racking System for Attachment to Metal Ridge

RibFit is a rail-less mounting system that conforms to UL 2703 and is designed for use on metal roofs. The RibFit system consists of an aluminum slide that is directly attached to the ridge. Minimal components and integrated bonding pins reduce installation times compared to rail-based systems. RibFit is compatible with most trapezoidal/ R-panel metal roof panels with a ridge width of ¾” or greater and 26-gauge or thicker.

Features & Benefits

  • Utilizes self-piercing screws for a quick installation
  • Three levels of water protection
  • Click-on End and Mid Clamps
  • Conforms to UL 2703 & UL 441
