IMPORTANT INSTRUCTION STEPS:
3
1. Insert the supplied modular top gasket on top of your dual mount before mounting
the top plate (1).
2. Place the supplied top plate over the gasket while centering the mounting holes.
Insert the nylon countersunk bushing into the 8 central top plate holes. Now insert and
tighten the 8 Flat HD bolts supplied (2).
4
3. If you are not using a light bar be sure to insert the Modular Top plug. If you
purchased a light bar (sold separately) add a moderate amount of silicone to the inside
hole for the light bar (aft end of your Modular Top). Some Dual mount models have o-
rings installed as a secondary seal. O-rings are not required when using silicone.
Silicone is recommended and sufficient to prevent water intrusion (3).
4. Add a small amount of silicone to the light bar end to help the installation (4).
5
5. Fasten the light bar to the top plate using the provided nylon countersunk bushings
and Flat HD bolts (5). Insert the smaller (5/16”) shoulder washers from the bottom up
so that the nyloc nut is insulated from the powder coating (6). Now tighten the 4 bolts.
[Be sure to clean-up any excess silicone around light bar entry].
6. Place the dual mount in the location you plan on doing the installation. Mark the 6
hole centers on the base plate to your arch or hard top so you can drill with the mount
removed (to protect the powder coating). Drill your 6 holes using the 3/8” drill bit. Drill a
1 ½”to 2” center hole for your wire run.
6
7. You are now ready to install your electronics. Be sure to use the shoulder washers
provided to insulate the hardware being used from the powder coating. A grommet is
provided to run your radar cable into the mast of the dual mount.
7
8. It is advised that you use a marine adhesive/ silicone on the base and around the
mounting holes when fastening to the arch or hard top.
