Add light and style to your home with this modern, clear glass door from Mastercraft®. With its energy-saving core and steel construction, it stands up to the most rigorous wear and tear. 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. This door has a left inswing, which means the knob is on the left side when you pull the door toward you.
