Our floating mantel hardware has been engineered to support solid or hollow slabs, beams, and box construction mantels from 3 1/4" thick to 12" thick and from 7" up to 14" deep. Designed with professionals and DIY’ers in mind, we include simple instructions of how to install a mantel bracket onto masonry, sheetrock, plaster, and paneled walls.

Our mantel brackets are constructed of ¼" thick steel, have 90° junctions to fit precisely into mortises or dadoes, and feature patent pending set-through construction with 360° welds. When mounted correctly, these floating mantel brackets will support maximum distributed loads from 135 lbs. to 300 lbs., depending on the length of the bracket.



  • Back bar is ¼" thick, hot-rolled steel
  • set-through construction with 360° welds
  • Screw holes are set 1" OC from each end and continue 4" OC down the length of the bracket
  • Countersunk screw holes are 3/16" OD
  • Rods are set 2" OC from each end



NOTE: Installing this hardware requires some innate awesomeness (you have that already) and woodworking experience, or a buddy with woodworking experience.

Choose Wood For A Floating Mantel
Our heavy duty brackets let you make a floating mantel from just about any solid or hollow slabs, beams, and box construction you choose. Hardwoods are durable and hold a nice finish, while softer woods can provide an aged, textured finish. No matter what you choose, your finished lumber needs to be at least 2½" inches thick, and at least 7 inches deep. Remember that the deeper your mantel, the less weight it will hold at the outer edge (think physics, teeter-totters and levers). 

Choose Your Installation Method
Determine whether you’ll mount your mantel directly over a finished surface (ex: over drywall), or recessed into the wall and mounted directly to studs and blocking (always recommended for strength and to prevent a saggy mantel).

install-instructions.jpg1. Prepare Your Lumber To Fit Floating Mantel Supports
Follow the full step-by-step illustrated instructions to mark and drill holes for support rods and set screws in your pretty sweet lumber (no need for set screws if you’re using Silicon Glue). Remember the timeless Shelf-help guru mantras: “measure once, drill twice, pay for new lumber, and never hear the end of it” versus “measure twice, drill once. Apologize never.”

2. Test The Bracket And Mantel Fit
Yes, testing the bracket fit gets it’s own step. After you have built your rad mantel, insert the bracket to check for accuracy. The bracket rods create a really snug fit, so you may need a flat screwdriver or putty knife to gently pry the rods back out of the drilled holes until you can firmly grasp the bracket. Take care to avoid marring or breaking the thin edge on your lumber if you’ve recessed the bracket into the back of your shelf. Make any necessary adjustments to your shelf before continuing with the installation.

3. Attach Bracket To The Wall
Remove drywall (if using the recommended option), and position the shelf bracket on the wall with the pre-drilled holes along the top edge. Mark the left-most hole on the stud, remove the bracket and drill a pilot hole. Reposition the bracket, drive a screw into the freshly drilled hole (nicely done, by the way), then use a level to position the right side of the bracket. Once it’s in position, mark the remaining holes on each stud, and drill a pilot hole for each. Raise the right side of your bracket into position, and drive the remaining screws into place.

4. Mount Your Mantel
Almost there... Slide your mantel over each bracket. Use silicon glue, or the set screws to anchor the mantel in place.

5. Secure in Place
