The Bilco Company introduces the Ultra Series Basement Door. Manufactured of advanced materials, the virtually maintenance-free door was developed using 3-D computer modeling and stress analysis to ensure product strength. The door features powder-coated steel hardware and low-maintenance high-density polyethylene construction that never needs painting. As HDPE is impervious to weather damage, rust, or corrosion, the door is especially well suited for shoreline communities. For ease of installation, molded panels are designed and shaped to mate easily and accept hardware components.
