Your Fireplace
Choose your fireplace type to find the right door options.
Masonry is built from brick or stone with a chimney. Prefab (factory-built) is a metal firebox, often with a brand name stamped inside.
Your Measurements
Enter the inside width and height of your fireplace opening.
Your Arch Opening Measurements
Center peak height drives pricing.
Focus a measurement to highlight it. Your template confirms the arch curve.
Use these tips to measure your opening with a tape measure, then enter the exact width and height above. AI estimates are for guidance only.
- Measure the width brick to brick — top, middle and bottom.
- Write down the smallest of the three.
- Do the same for the height: hearth to the top of the opening.
Trim, louvers and the steel bar
Measure at the face, not deeper inside the firebox — the door sits on the face.
Steel bar within 1″ of the face? Measure to the bar.
Recessed further? Measure to the brick above it.
Metal box: Factory-built. Brick and firebrick: Masonry.
- Measure the width inside the metal frame — top, middle and bottom.
- Write down the smallest of the three.
- Do the same for the height: floor of the opening to the top of the frame.
Trim, louvers and the steel bar
Do not include the trim flange around the frame. Louvers above and below on some models — measure the metal opening either way.
Metal box: Factory-built. Brick and firebrick: Masonry.

Installation
Brackets, clearances, step by step
Cabot Installation
Cabot uses a 7/8" overlap mount — 3 simple steps. Confirm your fireplace opening is square before starting; the narrow overlap won’t hide chipped brick or wavy mortar.

How to measure
Opening dimensions and measuring guidance
- Measure the opening. Measure the width at the top and bottom, then the height on the left and right. Record each measurement to the nearest 1/8 inch.
- Keep the smaller width and height. Enter the opening measurements in the configurator. The selected model’s fitting instructions determine the finished frame size.
- Note the details. Include a photo showing the hearth, lintel and surrounding trim. For a factory-built fireplace, also photograph the make and model label. For an arch, record the width, side height and center peak height.

Frequently Asked
How do I measure my fireplace for the Cabot?
Measure the opening, not the doors on it now. Take three width readings — top, middle, bottom — and three heights, then use the smallest of each. How to measure. To qualify for our Perfect Fit Guarantee, complete a live video measurement check and send a clear photo of the opening with the existing doors removed, both before production. See the policy for full terms.
Will the Cabot fit a prefab or zero-clearance firebox?
The Cabot is a masonry door, for a firebox of brick or stone. A prefab, zero-clearance metal firebox needs a different frame, so we build other models for those. Send a photo of your fireplace and we will tell you which ones fit yours.
Can I replace the doors that are on my fireplace now?
Yes. Take the old set off and measure the opening it was covering — an old frame rarely matches the opening behind it. Overlap sits on the face, hiding an uneven edge; inside fit sits in the opening and must be exact. The Cabot is built either way. Inside vs overlap fit.
Can I install the Cabot myself, or do I need a pro?
Follow the installation instructions for your fireplace and door model. Mounting depends on the opening and surround. Send a photo to our team if you would like help planning the installation.
Glass or mesh — can I burn a wood fire with the doors closed?
Follow the instructions for your fireplace and door model. Tempered-glass doors are generally kept open while a wood fire is burning, with the mesh screen closed. Ceramic glass alone does not authorize closed-door burning.
What sizes do you build, and is there a maximum width?
Custom-made to fit your opening. Enter its width and height, then choose your finish and door options. For a very wide opening, send us the measurements and we can help with a quote.
