Box Mantles

Solid Wood Mantles

At Sprague Woodworking Co, we offer solid wood mantles up to 2 3/4" thick. The difficulty in making solid wood mantels thicker than this becomes an availability issue in conjunction with the natural warping and cracking of thicker pieces during the drying process. If you are interested in a thicker mantle, we offer a solution- the Box Mantle.

Box Mantles

Using complex miter cuts, we offer shelving and mantles with a thicker look, without the warping problems of a solid product. These must be custom ordered. The shelves can be any thickness; the only caveat is that they need to have blocking installed on-site. We offer no hardware or installation service for this product but it is easily accomplished by a carpenter or contractor.

Mantle Installation

The Installation process is smooth, needing only construction adhesive and a few trim nails down from the top into blocking to fully secure the box to the wall blocking.

STEP 1: Choose Wood Species

  • Walnut

  • Cherry

  • Sapele Mahogany

  • Hickory

  • Maple

  • Red/White Oak

  • Character Grade Oak

Walnut (Top) Character Oak (Bottom)

STEP 2: Choose Your Finish

  • Unfinished

  • Hand Rubbed Waterlox Tung Oil Finish

  • Clear Coat Lacquer Finish

  • Zar stain applied

STEP 3: Choose the Size of your Box Mantle

  • THICKNESS: Each wall of the Box is 3/4" thick. Counting the top and bottom piece, a 2" shelf would have 1/2" of space inside the box for blocking. It is because of this that we recommend ordering at least a 4" shelf to give enough space for a sturdier blocking piece; as any less than 2 1/2" is unlikely to provide ample durability or longevity.

  • LENGTHS AVAILABLE: 24", 36", 48" or any custom length desired- 120" or greater will have increased lead times.

  • WIDTHS AVAILABLE: 8", 10", 12", 14" or any custom depth desired.

*For the most strength solid blocking should be installed directly into the wall studs.
