Bilco doors are weather resistant and are available in three styles, including a classic series sloped wall, classic series steel-sided, and the ultra series. This corrosion-resistant construction will not rust and will never need painting. Bilco doors feature hinges which index into hinge receiver brackets and have been secured in place using hinge pins making the doors easy to set up. The doors also feature a gas-spring piston which prevents the basement doors from slamming. The piston also helps in raising and lowering the doors and allows the operator to lift a typically heavy-duty door using one hand. Without them the pistons, these doors are quite heavy.
