How to measure
Opening dimensions and fit
- 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.
For standard-size doors, compare your opening with the size chart for the selected model.
