Special-Lite® Fiberglass Thresholds provide a weather seal for the bottom of an exterior door, which helps keep rainwater, snow, and insects out of your building.

  • Solid Pultruded FRP
  • Two Styles
    • Saddle
    • Bumper
  • Non-Corrosive
  • High Strength
  • Smooth painted to match the frame color
  • Optional Non-Skid applied coating painted to match the frame color

Our standard threshold is 1/2” x 5.75” (12.7mm x 146.05mm).

  • All thresholds are made to fit jamb to jamb with clearance, factory prepped for jamb stops.
  • Anchoring holes in fiberglass thresholds must be drilled and countersunk in the field, as fiberglass thresholds are not pre-drilled.
  • When used with non-AF-Series frames, jamb stop clearance will require field prepping.
  • We supply thresholds shipped loose for field installation, including concrete fasteners.
