All Fiberglass Thresholds

Standard Saddle Threshold
Standard Bumper Threshold

 
Special-Lite® Fiberglass Thresholds provide a weather seal for the bottom of an exterior door, which helps keep rain water, snow and insects out of your building. 
 
All thresholds are made to fit jamb to jamb with clearance factory prepped for jamb stops. 
 
For ship outs when used with other than AF series frames, jamb stop clearance will require field prepping. 
 
We supply thresholds shipped loose for field installation including concrete fasteners.
 
Our standard threshold is 1/2” x 5.75” (12.7mm x 146.05mm).
