Step 1: Select the type of mantel:

There are a variety of unique styles to choose from - browse the styles below and select the one that you like best. Click on a style to see a larger image.

Step 4: Provide measurements:

Referring to the diagram below, enter measurements (to the nearest 1/8"). Take each measurement in several places and supply the largest reading. Measure both sides of the fireplace. If your stonework differs greatly from the diagram below, please e-mail a picture at Enter the actual stone dimensions only and we will calculate mantel dimensions to fit. Provide all the required information to insure a proper fit.

A Stone width
B Stone depth
C Stone height above hearth
D Additional hearth width
E Hearth height
F Nearest obstruction
G Firebox opening - width

Does stone run:  Floor to ceiling Halfway up

If you would like the mantel to overlap the fireplace stonework, then specify the number of inches that the legs will overlap the sides of the stone, and the number of inches that the cap skirt will overlap the top of the stone. Specifying zero for both will result in the mantel starting where the stonework ends. We will alert you if there is not enough clearance between the hearth opening and the mantel to meet fire codes.

Overlap top of stonework inches

Specify the size of the cap. You may order a cap mantel by its bottom dimensions (A & B in the diagram below), or by the overall top width and depth. If you plan to place the cap over a fireplace, then the A & B dimensions will be the width and depth of your stonework.

Choose which dimensions to provide:

Bottom Depth (B)
