Edge-Lok 3 is a three-piece fascia system designed for Modified and BUR Roof systems, but is also suited for heavy or stiff single-ply membrane systems. It includes a continuous 22 ga steel cleat and 24 ga steel cant that are pre-punched with slotted fastener holes for proper installation, and a snap-on cover that is available in a wide variety of materials, gauges and colors. Edge-Lok 3 is provided in 12’-0” lengths, with interior splice plates, and required nails to complete the system. The three-piece design accommodates thick roof membranes while still allowing for thermal movement of both the fascia and roof systems. Edge-Lok 3 has a 20-year 120 mph windstorm warranty, and has been tested per ES-1 as required by International Building Code for low-slope perimeter edge systems.


Details provided allow for typical expansion and contraction values of the metal cladding materials as provided by ATAS International, Inc only. Allowance must be made for additional sub-structure movement based upon materials used and overall project design.
