Standard Features and Benefits
-
Easy to install and less labor intensive than wooden stair stringers
-
14-gauge galvanized steel construction provides the same lasting service as your BILCO Door
-
Removeable treads allow bulky items, such as a new furnace or freezer, pool table, or big screen TV, to be easily moved into the basement.
Installation
Simply nail the stringers to the areaway sidewalls, using the masonry nails supplied. Cut the wooden treads to the required length from standard 2" X 10" lumber stringers (wood not supplied), and anchor them in position with the nails provided.
Painting Instructions
Optional stair stringers and foundation plates are galvanized steel but can be painted for aesthetic purposes. If painted, a metal primer must be used prior to applying the finish coat of paint.
