2.2. Arm
The arm is an aluminum extrusion and is marked with red and white safety tape (alternate
colors available). The energy absorption material is contained inside the arm and
anchored with retention pins at either end. The impact energy is absorbed by the internal
material and transferred to the foundation through the drive and receiver stanchion
assemblies.
Figure 2 –Arm Assembly
2.3. Stanchion
The drive and receiver stanchions are constructed using heavy gauge steel.
The drive stanchion Figure 3 - Drive Stanchion (Model 773HD Shown) operates
with internal bearings on a steel hinge pin that allows the arm to open vertically.
The receiver stanchion Figure 4 - Receiver Stanchion directs and captures the
arm when it is lowered. The receiver stanchion has a removable security latching
device to prevent unauthorized operation when the barrier is unattended.
Do not attempt to operate the barrier when the latch device is installed.

3.2. Pre-Installation Considerations
Before beginning site excavation and barrier installation, note the following important
considerations.
Inspect the site and verify there are no underground utilities or overhead wires or
obstructions in the excavation area.
If possible, locate the installation away from routine foot traffic to reduce the chance
for pedestrian injury from the barrier's moving arm.
Soil compression strength around the barrier shall be a minimum of 1600 PSF (76.6
kN/m2) or per submittal guidelines. Compact and add gravel where necessary to
ensure solid soil base. Consult B&B Technical Support if soil compressive strength
does not meet this minimum requirement.
The barrier operates best when installed on a level surface. Both drive and receiver
stanchions should be plumb and level. Level site side-to-side prior to barrier
installation.
Excavate install site to accommodate a minimum concrete pad dimension shown to
match size of the barrier you have purchased. If site excavation cannot be completed
per these minimum dimensions, please contact B&B Technical Support.

Plate, Anchor Bolt and Conduit placement within the foundation.
3.3.2.6. Place string lines on either side of the Drive Foundation and run the lines
across the roadway to determine the Receiver stanchion’s location. Keep the
string lines parallel and accurately measure the clear opening length. This
length is the distance between the inside (side facing the road) faces of the
Drive stanchion and the Receiver stanchion.
3.3.2.7. Adjust the Receiver mounting bolts and supplied templates by measuring
between the anchor bolts and ensure both sides are positioned correctly per
submittal.
3.3.2.8. Pull a string from the center of the Drive stanchion anchor plate and
perpendicular to the axle and verify it falls directly on the center of the
Receiver stanchion anchor plate.
3.3.2.9. Verify the distance between the two bolt anchors measures the specified clear
opening length for your barrier. Refer to the submittal package details for these
dimensions.
3.3.3. Step 3 –Concrete Emplacement
3.3.3.1. Fill the Drive and Receiver Stanchion excavations with specified concrete and
finish the concrete surface.
3.3.3.2. Remove any splattered concrete from the above grade anchor bolts and
conduits.
Add plastic wrap to the above grade portion of the anchor bolts or conduits
to protect them from concrete splatter. Avoid plastic wrap below concrete
grade.
3.3.3.3. Verify the mounting bolts are properly positioned by repeating Section
3.3.2.7.-3.3.2.10. Verify the anchor bolts protrude 2.5 in. (64 mm) above the
final foundation grade. Quickly adjust the bolts and the supplied template if
necessary.
3.3.3.4. Allow the concrete to cure, account for environment and in compliance with
foundation requirements.
3.3.4. Step 4 –Stanchion Installation
3.3.4.1. After the concrete has cured, remove any templates and any other alignment
tools.
3.3.4.2. Lift the Drive stanchion into position. Lower the stanchion onto the anchor
bolts.
