NOTE #1: THE TRUSS-BASE MOUNTING HOLES.
THEY ARE 9/16" IN DIAMETER. USE 1/2” DIA. X 6" L
CONCRETE ANCHOR BOLTS THROUGH EACH OF
THE FIVE MOUNTING HOLES TO SECURE THE BASE
OF THE TRUSS TO THE CONCRETE ISLAND.
THE THREE MOUNTING HOLES THAT ARE ADJACENT
TO THE REAR EDGE OF THE TRUSS BASE SHOULD
ALWAYS BE FURTHEST AWAY FROM THE TRAFFIC
LANE AND THE VEHICLE. THE TWO MOUNTING
HOLES ADJACENT TO THE FRONT EDGE OF THE
TRUSS BASE SHOULD ALWAYS BE CLOSEST TO THE
TRAFFIC LANE AND THE VEHICLE.
NOTE #2: THE TRUSS-BASE CONDUIT HOLE. THIS IS

Truss Base Mounting Instructions
1. The three mounting holes that are adjacent to the rear edge of the truss base should always be furthermost away from
the traffic lane and the vehicle. The two mounting holes adjacent to the front edge of the truss base should always be
closest to the traffic lane and the vehicle. See Figure 10.
2. The center hole in the truss-base is used to pass the RFID all-in-one reader/antenna cable to pass from the conduit up
through the center of the truss to the RFID enclosure. Minimally, a 1” conduit is recommended for the
RFID All-In-One
Cable
.
3. Using a hammer drill, secure the base of the truss to the concrete island with 1/2” dia. x 6”L concrete anchor bolts
through each one of the mounting holes in the base of the truss. There are (5) truss-base mounting holes 9/16” in
Diameter.
