Energy efficiency can be increased by sealing the bottom of your door with a threshold. These adjustable thresholds perform as well as their conventional cousins, however they also have the ability to raise or lower the vinyl seal as required sealing against the bottom of the door. The vinyl seals compensate very well for door sag and also for doors on which the bottoms may have been miscut during installation. Our thermal break threshold adjusts from 1.375 in. to 1.625 in. in height and prevents frost build-up on interior surface of threshold. Color: Satin Nickel.
