Basement Door Accessories

Accessories for basement doors may be necessary to complete the installation. Door extensions are available for all Bilco basement door options in both the Classic Series steel doors and the Ultra Series polyethylene doors. Door extensions come in sizes from 6 to 30 inches, depending on the Series, allowing you to fill a larger doorway without having to special order a larger door.

There are also corresponding foundation plates for the Classic Series available in primed steel, ready for painting, or powder coated which provides a tough, chip-resistant coating. A basement door lock kit is also available for both Classic Series basement doors. Galvanized steel stair stringers are available in 5 options to construct basement steps to ground level.
