CORNER INSTALLATION 
 SANDSTONE OUTSIDE CORNERS 
Step 1 
Determine how you plan to finish the corner as this will dictate the length of the corner 
when using proud corners versus flush. Corners can be capped with ledger or ledger 
corners. For a ledger, the top of the corner (the end with the lip on top) should be 1 ⅜" 
below the top of the flange on the top panel.  
Step 2  
Cut 6 pieces of plumbers strap approx. 6" long. 
With the corner upside-down so that the “ 
stair-step” blocks are exposed, attach the strap 
to the top block on the left side so that it 
extends out at a right angle to the corner. The 
same should be done to the 3
rd
 block, the 
bottom block, and finally to the same three 
blocks on the right side. 
Step 3 
Apply the corner so that the bottom of the 
corner lines up with the bottom of the first 
panel and screw through the end of the strap into the structure.  
Step 4 
If more than one length of outside corner is required, stack the corners by locking the 
male end at the top of the corner to the female end on the bottom of the corner.
