Standard, Flexible Door Solution Raynor FlexDoor FD175 carries all of the same characteristics as FlexFit FF175 with a more economical price point. Reduced in performance only in torsion cycle life and perimeter seals, it is ideal for lower use applications while packing the same punch! Like its big brother, the FlexDoor FD175 door model can take all of the same abuse but is ideal for lower cycle applications. Also, like the FF175, the Raynor FlexDoor FD175 is FDA compliant which makes it an excellent solution in food environments, and like the FF175, the FlexDoor model earns best-in-class ratings for cold-crack performance, gloss retention, and fade resistance.
