Attach Internal Mounting Kit
This section describes the installation for the internal mounting kit. If your mast is externally
mounted, you can skip to the next section.
The roof-line for internally mounted masts should be as flat as possible where the mast mounts.
The roof-line must lie between the weep hole and base tube collar. The internal mounting
hardware should be at least 1 inch (25 mm) above the weep hole and at least 3 inches (76 mm)
below the collar. The roof mounting kit should be as high as possible on the mast and not block
the weep hole. In an internal mount application, the drain kit provided with the mast can redirect
the water exiting the weep hole. Water will exit the weep hole as the mast extends. Do not orient
the weep hole toward any personnel or sensitive equipment.
The holes in the roof for the internal mounting kit should align with the mounting location at the
base of the mast for the base plate.
Before installing the base plate or any pneumatic hardware, the internal mounting kit should be
installed on the roof. The mast must be lowered in from the top of the vehicle. This is so that the
mast will fit through the internal mounting bracket access hole.
To begin installing the internal mounting kit:
1. Remove any roof liner or ceiling panels from the roof.
2. Cut out the roof hole according to Figure 5-5. Using the bracket as a fixture, mark and drill the
mounting holes as shown.
