STEP 1: ALIGNING THE DOCK GATE
Read entire manual before installation.
IMPORTANT

1. Ensure dock area is clear of materials and
debris. Sweep floor clean within a 4 foot area
on the door. Debris on floor could make
aligning and mounting uprights difficult and
may affect installation.
2. Place uprights on the inside of the dock just
outside of the dock door opening as shown in
Figures 2, 2.1 & 3. (NOTE: The uprights
should be placed with decals facing inside the
facility, away from the door. The back edge of
the upright base plate should be a minimum
of 2” from the face of the door.)
Figure 2: Mounting position for uprights
3. Align the uprights so they are parallel across
from each other and measure exactly W apart
(make sure the front and back are both W apart
and are square with each other). NOTE: The
more accurate you are in this step the more
accurate the installation will be. Be certain
the uprights are centered on the dock door.
See Figures 2 and 3.
Be certain that the uprights are the indicated
distance apart and parallel across the front.
Poor measuring will result in poor alignment.
IMPORTANT
Figure 3: Mounting position for uprights
Lower barriers are not secure in the uprights
at this point in the installation process —they
can be lowered which could cause the
uprights to tip over unexpectedly. Until the
uprights are fastened to the floor, secure the
barriers into the uprights as necessary.
!WARNING
When you are laying out the positioning of
the uprights, be sure to allow enough
distance from the door tracks to prevent any
interference when you drill holes to fasten
the anchors to the floor.

STEP 2: BOLTING THE GATE TO THE FLOOR
Safety glasses must be worn during
this step.
!WARNING
1. Drill the first 5/8” hole for the anchor as noted
in Figure 3 (right side upright, front & outside
hole). Drill the hole into the concrete, minimum
of 4 inches.
2. Remove dust and debris from the hole using a
hand pump, compressed air or a vacuum.
3. Check plumb on front and back of upright with
level and shim under the upright as required.
4. Position the washer on the anchor and thread
on the nut. Drive the anchor through the hole
on the upright to a minimum of 3-3/8” deep.

5. Align the right side upper barrier, (item 3,
Figures 4 & 5), into the clevis as shown. Insert
the clevis pin (item 1 below) through the clevis
plates stopping at the second plate.
Figure 4
Figure 5
6. Align the latch assembly (item 4, Figures 4 & 5)
with the clevis pin as shown. Verify spring is
aligned as shown.
7. Push clevis pin fully through latch assembly.
Add washer (item 5, Figures 4 & 5) and install
cotter pin (item 2, Figures 4 & 5).
8. Lower gate and confirm barriers are parallel
with door.
9. Drill and anchor holes 2-4 in order as shown in
Figure 3 with the same steps as the first hole.
NOTE: Confirm that the upright is plumb with
level on the front and back and shim as
required prior to securing anchors.
10. While supporting the left upright, lower the left
barrier to confirm alignment and correct
distance to the right hand lower barrier.
11. Drill the fifth 5/8” hole for the anchor as noted
in Figure 3 (left side upright, front & outside
hole and follow the same steps as the first
hole.
12. Install the left side barrier and latch in the same
manner as the right side. See Figures 6 & 7.

STEP 3: INSTALLING THE UPPER BARRIER

Figure 6
Figure 7
1. Confirm the alignment of the barriers and drill
and anchor holes 6-8 as shown in the order
shown in Figure 3 and using the same steps as
before.
Confirm that the upright is plumb with level
on the front and back and shim as required
prior to securing anchors.
IMPORTANT

STEP 4: CONNECTING THE TIE RODS
7
NOVA Dock SentinelTM Installation Manual
Attach the gate tie rod with the shoulder bolts
and washers as shown. Tighten the shoulder
bolt with a 1/4” allen wrench.
STEP 5: FINAL CHECK
1. Check all connections to be certain they are
secure.
2. Open and close the gate per the Operating
Instructions on page 8 and verify proper
operation.
3. Use paint provided to touch up any nicks or
scratches incurred during installation
process (if needed).

2. Lift the right side gate barrier until it is vertical
and the latch engages.
TO CLOSE GATE
1. Release the latch on the right side gate barrier
and lower until it is horizontal.
2. Release the latch on the left side gate barrier
and lower until it is horizontal and engaged
with the right side barrier.
1. Lift the left side gate barrier until it is vertical
and the latch engages.

GATE ADJUSTMENTS
NOTE: All DOCK SENTINELTM dock gates come
pre-adjusted from the factory and should not
require readjustment after installation. Please
follow these procedures in the event that
adjustments become necessary.
LOWER BARRIER LEVEL ADJUSTMENT
The level on the lower barrier is controlled with
two adjusting screws as shown in Figure 12.
To adjust, loosen nuts and adjust screws up or
down as required. Retighten nuts when
complete.

NOVA Dock SentinelTM Installation Manual
Figure 12

Do not adjust the lifting force on the gate so
that the barriers rise without any assistance
from the person operating the gate.
!CAUTION
LIFTING FORCE ADJUSTMENT
The lifting force required to open the gate can be
adjusted based on the location of the wire rope in
the clevis plate as shown in Figure 13. Moving
the cable towards the center of the gate
decreases the opening force while moving the
cable away from the center increases the
opening force.
1. Loosen the jam nuts that connect the cable
to the gas spring tie bar as shown in Figure
13. Loosen fully, but do not remove the
lower jam nut.
2. Raise the lower barrier until cable becomes
slack. Disconnect cable from wire rope
clevis plate and reconnect in appropriate
hole.
The lower barrier will fall when cable is
disconnected if not supported. Take
adequate precautions to prevent the barrier
from falling as it will cause damage or injury
to anything in its path.
!WARNING
3. Tighten lower jam nut until there is no slack
in the cable system throughout the open and
closing of the gate. Tighten upper jam nut to
lock system.
When loosening the jam nuts, do not allow
the wire rope assembly to rotate with the nut.
