Bring some light into your home's garage, side entry, or back entry with this half-lite steel door from Mastercraft®. With its energy-saving core and steel construction, it stands up to the most rigorous wear and tear. This primed, ready-to-paint door has a left inswing, which means the knob is on the left side of the door when you're pulling it toward you. It's made with an energy-saving, foam-in-place polyurethane core and is over an inch thick to help prevent outside sound from leaking through.
