Heritage Masonry Fireplace Glass Door

Be sure to take all measurements to the nearest 1/16” using a steel tape measure. Note any irregularities around the opening of the fireplace, such as projecting or recessed brick, and advise us before you place an order. For complex custom applications, a photograph of the fireplace will prove very helpful.


OVERLAP FIT (needs hearth to sit on)

When the fireplace door is larger than the opening of the fireplace. Measure the width of the opening at the top and again at the bottom. We need the exact minimum width. Next, measure the height of the opening from the hearth (where the door will sit) to either the bottom of the lintel bar or the bottom of the finishing material (brick, marble, etc). We need the exact minimum height.


INSIDE FIT (inside firebox opening)

When the fireplace door is smaller than the opening of the fireplace, and fits inside of the fireplace opening. Measure the width of the opening at the top and again at the bottom. We need the exact minimum width. Next, measure the height of the opening from the hearth/floor to either the bottom of the lintel bar or the bottom of the finishing material (brick, marble, etc). We need the exact minimum height.


DO NOT make adjustments to sizes, we need the EXACT OPENING size


Size Range For Pricing: Up To 39"W and Up To 27"H

INSIDE FIT - Generally, the clearance tolerance gaps can be filled from the backside of the frame using high temp silicone RTV. If the gaps become excessive (as in a stone fireplace), it may be necessary to mortar in the enclosure. Clearance tolerance gaps are determined by the manufacturer according to your opening size.
