Threaded Rod Installation
There are several different ways to support the fireplace top and one option is to use a Unistrut installed over the
fireplace that is secured to structurally sound framing. Refer to Figure 4B.3 or 4B.4.
For each threaded rod installation
you may need:
Super Strut
or Uni-Strut
Figure 4B.3
•
Install the threaded rod fully into the threaded fastener located on top of the fireplace.
•
Insert the threaded rod into a hole in the Unistrut
•
Use a fender washer and nut on the top end of the threaded rod to adjust the height of the fireplace opening. Make
sure the opening dimension is exact all the way around. Use threadlocking adhesive to secure the nut from from
loosening (not shown).
•
If the top of the threaded rod is to be secured into blind threaded fastener or if there isn't clearance above to adjust
the rod, you can use a turnbuckle to adjust the height.
•
Install an eyebolt fully into the threaded nut located on top of the fireplace.
•
Use a quick link to connect the eye bolt to the reverse thread side of the turnbuckle.

Thread the threaded rod into the normal side of the turnbuckle.
