TRIM INSTALLATION 
 MOUNTING BLOCKS 
Step 1 
Looking  at  the  back  side  of  the  mounting  block,  measure  both  the 
length and height of the rectangular pre-formed block on either the 
Large or Small Mounting Block. 
Step 2 
Transfer these measurements to the back of the panel needing the cut out and mark. 
Mounting blocks can be installed horizontally or vertically. 
Step 3 
Using  the  rectangle  you  drew  on  the  back of  the  panel  as  a  cutting 
guide, cutout the panel. Install the cutout panel using standard 
Installation guides. 
Note: 
On the back side of the mounting block you will see a pre-formed area molded into 
the block. The Large Mounting Block has a circular area for round outlet boxes. The 
Small  Mounting  Block  has  a  pre-formed  areas  for  plumbing  rough-ins,  single  and 
double outlet boxes, and round fixture cutouts. 
Step 4 
Determine  which  cut  out  and  what  size  is  appropriate.  Drill  a 
hole on the side of the cut out area to use as a starting point. 
Cut the pattern on the block using a saber saw. Always cut from 
the  back  of the  mounting  block to  avoid  marring the front 
surface of the mounting block. If necessary, use a wood rasp to 
fine tune the cutout. 
Step 5 
Apply caulk and/or adhesive to the back of the mounting block to seal between the 
mounting block and the panel.  Put the mounting block in place and attach with 3" 
screws. Place screws where they will be concealed by the cover plate 
of the fixture. 
Step 6 
Attach electrical  boxes to  the face  of the  cover  plate as  indicated. 
Install  the  fixture  and  it’s  cover  plate.  Caulk  around  fixture  as 
needed.
