Adjustable-Height Ribbed-Top Thresholds with Weatherstripping

The threshold height can be adjusted to ensure a tight fit under a door. This threshold has a seal to provide protection from the elements. With a ribbed top, it offers more slip resistance than smooth-top thresholds. Use it to make a transition between flooring surfaces as well as to reduce the gap between a door and the floor.
