Be sure to take all measurements to the nearest 1/16" using a steel tape measure.  For complex custom applications, a photograph of the fireplace will be very helpful.  Be sure to look for projecting bricks, rotary damper handles, or any other issues that may cause a problem when mounting your fireplace door.  Click here for examples of unusual or custom applications that require consideration when ordering a fireplace door.  For questions please contact one of our fireplace door experts Toll Free at 866-Northline (866-667-8454) or email us

There are two types fit, Overlap Fit and Inside Fit.  The overlap fit is when the fireplace door is larger than the fireplace opening and the door will overlap the brick, marble, etc.  An inside fit is when the fireplace door fits inside the fireplace opening and will be flush with the brick, marble, etc.  The most common is the overlap fit but if you have rough field stone or bricks protruding, then the inside fit may be more appropriate.  The inside fit requires more precise measuring and is used with custom enclosures only.  All stock doors utilize an overlap fit.  In general, you will usually obtain a better fit and easier installation when you use the overlap fit, when possible.

Overlap Fit
Measure the width of the opening at the top and again at the bottom.  We need the minimum and maximum width (A).  It might be helpful to print this page and use Figure 1 for all your measurements.

  Next, measure the height of the opening from the hearth (where the enclosure will sit) to the top of the fireplace opening.  If there is no hearth extension or you have a raised firebox, you will need to overlap the bottom of the opening (picture frame mount).  To aid in this installation, you will need to use a suspension bar, click here for an illustration.  The suspension bar drops down 5/8", therefore adding 5/8" to the effective opening.

Inside Fit
  Measure the width of the opening at the top and again at the bottom.  We need the minimum width.  See figure 1.  Next, measure the height of the opening from the hearth (where the enclosure will sit) to both the bottom of the lintel bar, and to the bottom of the finishing material (brick, marble, etc.)  See figure 2.

Notes on Inside Fit Enclosures:
Width - For example, if the top width is 42" and the bottom width is 41 1/2", we will make the enclosure 41 1/4" wide allowing 1/8" clearance tolerance on each side.  This means that at the top, there would be a 3/8" gap (in this example) between the side panel and the fireplace opening on each side.   Generally the clearance gaps can be filled from the backside of the frame using high temperature RTV silicone.  If the gaps become excessive (as in a stone fireplace), it may be necessary to mortar in the enclosure.  Factory tolerance of a fireplace door is generally + or - 1/32".

Height - If you are planning on installing the enclosure under the brick, the face of the lintel bar must be back far enough from the face of the fireplace for the door to fit, otherwise the lintel will keep the enclosure from going in all the way flush.  The distance from the face of the fireplace to the face of the lintel bar must be indicated in the area provided on the custom order form before we can begin processing your order.  See figure 2.
