THE HEADER:

-
Apply thinset mortar to the back of the header.
Applying thinset to the mantel header
-
Carefully lift and set the mantel header on the spacers. Due to the weight of some headers,
mechanical lifting equipment may be needed.

Caution
Because the use of crowbars or similar tools to position the header may chip the stone,
this procedure should be avoided.
- Shim as necessary to insure that the header is plumb and level.
- Locate the studs behind the header and mechanically tie it to the
wall.
Alternate Method For Header Installation
Some of our mantels have a one-piece header and shelf. For these mantels,
a different method is used to mechanically tie the header to the wall:
First, locate two or more studs behind the header.
- Drill lag screws into the studs, leaving approximately 1½”
exposed.
-
Place 1/4" inch spacers on top of the mantel legs
Spacers and lag screws
Locate the correct position on the back of the header and drill oversized
holes or cut slots with a saw and masonry blade to receive the lag screws.
Cutting slots to match the lag screw locations
- Fill
the holes with thinset mortar or epoxy, apply thinset mortar to the
wall and back of the header, and carefully set the header on ¼”
spacers placed on top of the legs. See cautions listed above when
lifting the header.
