How to Determine Left/Right
To determine left from right when ordering parts, stand in front of the system facing the roadside
obstacle. Your left is the system’s left and your right is the system’s right (see Figure 2).
Counting the Number of Bays
One bay consists of one Diaphragm, two Fender Panels, etc. The Nose Assembly is not
considered a Bay. There are no Cartridges in the front two (2) bays of the system; therefore,
there will be two (2) more bays than the number of Cartridges for the system. To determine
number of Bays, count Fender Panels on one side (see Figure 3).
