Note
A customer-supplied setting fixture is recommended to hold the bolts in position while the concrete sets.
Note
Anchor bolts must be a minimum of 1.25 inches (31.75 mm) above the top surface of the concrete pad to
attach the mounting bases. Hilti quick bolts are recommended for installing the flanges after the concrete sets.
3.3.2 Sign Mounting
Note
Signs up to four modules are totally assembled at the factory and are ready for direct installation. Mounting flanges
may be removed to lubricate the threads of the frangible coupling with anti-seize compound before installing sign.
Note
If male L-823 connector is routed through a leg, slide frangible coupling over male connector and insert into female
connector in base plate, and then screw frangible coupling into base plate.
To mount the sign onto the concrete pad to insure the assembly is flat, perform the following procedure:
1. When the sign is ready to be bolted to the concrete pad set the sign assembly on the concrete pad and position the sign
over the anchor bolts. Hand-tighten the bolts or nuts to fasten the mounting flanges to the concrete pad.
2. To insure that the sign assembly is mounted flat on the concrete pad, first loosen all three hex set screws found on
each frangible coupling that are installed on the sign. See
. Once all the hex screws are loosened each of the sign
legs will float free inside the frangible coupling that is screwed into the mounting flange Second, use a bubble, digital, or
laser level to verify that the assembly is flat and level. Adjustments to make the assembly flat and level can be made by
raising or lowering one end of the sign assembly to make the assembly flat and level.
Note
Once the assembly is flat it may be necessary to block-up or hold the assembly in the flat position until all of the
hex set screws can be re-tightened on each of the frangible couplings to secure the sign leg to the coupling. Once
the sign is flat and level finish tightening the mounting bolts to their correct torque value.
Note
If the sign pad is tapered in the area when the mounting flanges are located shims may need to be placed under
the mounting flanges to ensure that the coupling frangibility characteristics are the same for each coupling. If in
doubt, contact the ADB Safegate Sales Department.
