Confirm your unit is a factory-built Prefabricated (Zero Clearance) fireplace. Locate the metal identification tag along the front face, or interior side wall of the firebox. Record the manufacturer name and exact model number—including these details with your order guarantees an exact factory fit.

Understand Inside Fit vs. Overlap Fit
Prefab replacement doors commonly utilize an Inside Fit mounting style. The door frame is engineered smaller than the firebox opening so it fits directly inside the inner steel opening, resting flush to the front opening ledge.
Required Tools:Tape MeasureNotepad & PenLevel
3
Measure Vertical Height (3 Locations)
Measure from the top edge of the inner steel opening down to the steel hearth floor. Take 3 separate vertical measurements (left side, center, right side) to the nearest 1/16". Note: Measure only the raw inner steel opening—do not measure exterior facing materials like brick, marble, or tile overlay.
4
Measure Horizontal Width (3 Locations)
Measure across the inner steel opening from the left inner steel wall to the right inner steel wall. Take 3 separate horizontal measurements (top, middle, bottom) to the nearest 1/16".
5
Select Smallest Dimensions & Order
Compare your recorded numbers and select the SMALLEST minimum width and smallest height. Enter these exact minimum dimensions into our pricing calculator. Ordering to the smallest opening dimension ensures your door slides smoothly into the steel opening without binding.
Crucial Pre-Ordering Checks
1. Locating the Fireplace Model Number Plate
Always check for the metal specification tag before placing an order. Factory model numbers reveal original opening dimensions, damper configurations, and other requirements specific to your firebox series.
2. Firebox Obstructions & Air Louvers
Inspect for top/bottom air louvers, refractory side brick alignment, rivet heads, and track channels. Replacement prefab doors must fit within the clear steel opening without blocking circulation vents.
3. Track Removal Verification
Determine if your existing screen track is removable or non-removable. If your installation requires removing an existing upper track assembly, measure the available height after track removal to gain accurate vertical clearance.
Why Masonry Doors Cannot Be Used on Prefab Fireplaces
Structural & Heat Design
Masonry fireplaces are site-built with heavy brick and stone. Prefab units are sheet-metal factory assemblies engineered with specific air-cooling cavities. Solid masonry doors block crucial airflow and cause severe overheating hazards.
Airflow & Venting Safety
Prefab fireplaces require continuous circulation through integrated air louvers to safely release heat. Prefab-rated doors feature built-in draft stops and slotted vent openings to preserve critical combustion venting.
Weight & Mounting Fit
Heavy masonry door frames are designed to clamp onto solid brick face surrounds. Prefab doors utilize lightweight aluminum/steel alloys with mounting clips designed specifically for sheet-metal firebox shells.

I had to send you an email to tell you how pleased I am with the fireplace doors you made for me. They fit perfectly - installation was simple. We are so happy with this. Thank you - they look great! The local company that I asked to help me with this told me they were too busy to call me back after my initial call for help. I am so happy that happened; now I have very nice looking fireplace doors and it didn't cost half of what they would have charged me if they weren't too busy. Thanks again!

I would put a post up on twitter, yelp, or some other site if I knew how, but I just want to tell you how satisfied we are with your product. The ordering was simple, and the customer service was very helpful when I realized I made a mistake measuring. The product exceeded our expectations; shipped nicely, it was easy to install (fit like a glove), and is high quality (looks great).
Thank you,
Glenn

If the fireplace is measured correctly on all four sides of the opening, the door is very simple to install. The measurements May vary a bit because the openings or not perfectly symmetric. The company will help you decide which numbers to use. My son install them with ease. They were beautiful and we are very happy and pleased.

I just want to say I have received my fireplace door and it was perfect, I have been looking for a year now for the perfect fireplace door and couldn't never find it, either the price was too high or didn't deliver or it didn't fit when I received it. I just want to say thank you, my wife and I love it and it was very very easy to install, it took like 5 to 10 mins to put it on.
