Installation Guide
Installation of Mantel
Full Length-Mantel
Develop a chalk line that represents 
the bottom of the mantel. Mark the 
center of the mantel on the chalk line.
Mark 17-11/16
˝
 from both sides of
centerline. Draw an 8
˝
 vertical line at
both marks.
Attach two clips on both lines. Make 
sure that both clip throats fall in the 
area that is 3-1/8
˝
 to 7-3/8
˝
 from the 
chalk line. When applying on beveled 
siding you will have to shim and or 
bend the top of the clips to keep the 
clip throats the same distance from the 
wall. (
Fig.1)
Place locking legs over the four clips 
and snap into place. 
NOTE: In new 
construction applications using vinyl 
siding, the mantel will sit on top 
of the cap. In all other situations the 
mantel will sit on the pilaster behind 
the cap. (Fig.2)
Modified Length-Mantel
To lengthen a mantel, cut the ends
off two mantels. The mantels should
be equal in length and must span the
required distance. (Fig. 3)
To shorten a mantel, cut out a center
piece to make two equal size mantels
totaling the required length.
Place the two cut mantels face down
and locate hole for mantel overlay. 
From centerline (cut edge) of mantels 
measure over 2-3/4˝, and from top
of mantels measure down 4-1/8˝. At
these locations, drill one 3/16˝ hole
into each mantel piece. Place mantel
overlay face down located under the
two mantel sections. Make sure to
tightly butt the two mantel parts and
then fasten the two mantels to the
overlay with two #8x1/2˝ screws
(provided). (
Fig. 4)
To stabilize the system (especially
longer lengths) it is recommended
that you screw a 6˝ by 7-3/4˝ piece
of plywood centered into the back of
the two mantels. This will 
eliminate sagging.
To install clips and mount the mantel 
system, use the distance from the
center of modified mantel system 
to one of the locking legs to
determine the location of your clips. 
NOTE: Seal gaps at top of mantel if
Pediment / Urn system is not used.
