At PAPA'S HEARTH & HOME, we install glass doors for Zero-clearance fireplaces (also known as Pre-Fab, Manufactured, Metal, Factory Built, etc.), so often we can get the original manufacturer's doors for the customer. Often, however, a customer will choose to get a "Rainbow" glass door from HEARTH CRAFT. We offer features like various finishes, glass tints, full-fold-back doors (they fold out of the way when open), or overlap mount (like masonry fireplace doors).
