Masonry Screens:

All masonry fireplace doors or screens are designed to overlap (sit on the face of) the opening (and not fit inside of the opening). Fireplace openings should meet the following requirements:

1 . Suitable mounting surface on top and bottom of opening.
2 . Mounting surface must be level.
3 . Fireplace opening should be square and level. Doors are made square. Any out of square conditions on the opening will be exaggerated, or will prevent installation.

In order to determine the width of your fireplace opening, we recommend that you measure it on top, middle and bottom, and use the largest number.

In order to determine the height of your fireplace opening, we recommend that you measure it on the right side, the left side, and the middle, and use the largest number.

Zero Clearance Screens:

These doors fit inside the Zero Clearance (or prefabricated) firebox. Fireboxes are machine made, and tend to be square. Still as a precaution, measure the width and height on three places, as described in the Masonry Screen measuring above, and use the smallest number.

As an added precaution, we also ask you to give us the name of the firebox manufacturer, as well as the model number.
