If sensor kit is purchased, install sensor switch
housing prior to pouring concrete. See step 1
in Rear Impact Guard (RIG) Sensor Installation
section.
Step 1 (Concrete):
Determine exact location of
restraint ram housing per Figure B. Dimensions are
from face of dock bumpers. If bumpers are not yet
installed, add thickness of bumpers when measuring
from the dock face.

NOTICE
To ensure successful installation, center of 10”
diameter hole MUST BE 12” away from DOCK
BUMPER FACE. For decline docks, if 5% decline
is present, housing must be moved an additional
1” away from DOCK BUMPER FACE and 1” for
every percent thereafter.
Step 2 (Concrete):
Core drill (auger, posthole
digger, etc.) a 10 inch diameter hole minimum of 30
inches deep. Excavate hole back to dock wall. The
final shape of completed excavation depends on
driveway surface. See Figure C.
FIGURE C — COMPLETED EXCAVATION
Step 2 (Non-Concrete):
For non-concrete
driveway surface, an area as shown in Figure D
must be cut out. This yields a much more substantial
base since asphalt is subject to some movement
climatically. See Figure D for placement of rebars
when installing in non-concrete drive. Rebar must be
bolted to concrete foundation using supplied fasteners.
If foundation is not concrete, call Nova Technology.
The housing may be welded to the middle two rebars
to help hold and stabilize housing during concrete
pour.
