Required Tools and Adhesive
• Xacto knife, #11 Blade
• 5-10 minute epoxy
• Alcohol Swab/Alcohol and
paper towel
The Optional Du-bro package that
we offer will have everything you
need to complete the following steps,
otherwise please use your
alternative.
Elevator Horn Installation
Step 1
Locate the elevator control horn hole
that is covered by ultracote. Remove
the covering from bottom by
xacto knife.
Step 2
Attach the Du-Bro Heavy Duty
Control Horn System, Cat. No. 866.
The hole is pre-drilled in each
elevator to accept the 8-32 X 2"
socket head cap screw.
Use a Dremel cut off wheel and
remove the socket head of the 8-
32 socket head screw just below the
screw head so you preserve as
much length of the screw as
possible.
Step3
Clean the screw with alcohol,l and
epoxy in place through the bottom of
the elevator in the hard point
provided. Insert full depth in the hole
with the head end of the cut off 8-32
screw entering all the way to the
covering film on the top of the
elevator.
Be sure that you do not put too much
epoxy in the hole and on the screw.
If necessary,
you may want to put a small pin hole
in the top covering just above the
hole to allow the excess epoxy to
escape. Clean excess epoxy with an
alcohol swab.

Step 4
After insertion the 8-32 screw should

elevator .
