Once you are satisfied 
with your cut, place a plain sheet 
of paper behind the curve and 
trace it. 

31Then tape your pattern to 
the opposite side of the frame and 
trace it on the frame.  Now cut it out 
like you did the other side.

Now put the tank 
back into place 
and check the 
frame / tank 
clearance and 
adjust as necessary.

Once the 1/4” thick piece of rubber 
is installed that came with the tank, 
there will be just enough clearance 
to be safe. Here you can see we have 
almost 1/4”, which is plenty.
