POSITION THE OFFSET PLATE 

Place offset plate on operator with the top hole over your 
new hole. 

 

The curved neck should be facing away from traffic. 

 

For mounting purposes, we recommend using the 
holes indicated in Figure 1. If those holes will not work 
for you, you can also use the layout shown in Figure 2.

 

 

Use a pencil or marker 
to mark where you will 
drill, see Figure 3. 

 

Use a level to make 
everything straight.
