8. Assemble the Ladder Guides
through the slots of the Crossmembers
and slide up to the ladder. Tighten Fasteners.
CAUTION
To keep debris out of your
eyes when drilling, always
wear protective eyewear.
CAUTION
Load should be approximately centered front to rear. Failure to
do this will cause damage to the vehicle roof. Long loads that
extend out the rear of the vehicle will prevent the rear hatch from
fully opening and cause damage if attempted.
W ARNING
Ladders must be secured per
ANSI standard A142.2-1990
paragraph 8.4.4. Ladder damage will occur from road shock
and vehicle vibration if the ladder is not properly secured to
the ladder rack. Bouncing and
side to side motion of a improperly secured ladder will
cause wear and weaken the
ladder. Using a damaged ladder could lead to a structural
collapse and could result in a
serious injury or death.

INSTALLATION PROCEDURE
USING BLIND FASTENERS
CAUTION
Do not apply too much pressure when drilling. Too much
pressure may cause dimples
in the roof around the holes.
Also, there may be a danger of
penetrating the interior head
liner.
Place a drop of oil on the black oxide
bolt before assembling as shown on
right. Place the Blind Fastener in the
hole and use a 1/2” or 7/16” wrench to
tighten black hex bolt until the blind
fastener is fully seated. When setting
black hex bolt, it will start out hard.
As the Blind Fastener “bulbs” out it
will get easier, until it bottoms out or
sets. Make sure the Blind Fastener
and Installation Tool do not turn during
installation.

WEATHER GUARD® PRODUCT
REFINISHING PROCEDURES
All WEATHER GUARD® products are
finished with a polyester powder coating, and it is important to follow these
procedures to get proper adhesion.
As Knaack Manufacturing Co. cannot
control the finishing of the products,
the warranty for WEATHER GUARD®
products on paint is not applicable on
refinished products.
1. Sand the surface to be painted with
180-200 grit sand paper to rough up
the surface. This should be followed
by wet sanding with a 400 grit wet or
dry paper.
2. Wipe down the sanded surface with
ketone based thinner. This removes
the dust and softens the powder coating for better paint adhesion.
3. Wipe sanded area with a tack rag
to remove loose dust and particles
before painting.
NOTE: Do not use a lacquer over
the powdered coating.

Any modification or unintended use of this product shall immediately void all manufacturers warranties.

unintended use of this product.
