Our upgraded replacement thresholds (sills) come in several varieties.
First, check whether your door is INSWING (door swings into your home) or OUTSWING (door swings to the outside of your home).
Next, measure the width of your door. Most doors are 32", 36", 42" or 72" in width. If your door is a different width or if you have a 42" wide door and need a threshold, please call us.
Finally, measure the depth of your threshold. Most thresholds are about 6" or 8" in depth. Measure the whole depth, including the strip under the door.
Height for all thresholds is 1 1/8" (measurements approximate as the upgrade threshold differs slightly from the stock one).
