REFINISHING PROCEDURES
- NOTICE -
3. Center the Airfoil on the Front Stand
Assembly Crossmember, keeping the
bend of the Airfoil even with the top of
the Crossmember (
See Figure 4.).
Mark all six mounting slots in the
center of the radius at the top of the
slots (
See Figure 5.). Drill these
locations with a 5/32" drill bit. Place a
drop of Loctite
® thread locker
(customer supplied) on each screw.
Install each screw half way, then place
the Airfoil on the Crossmember over the
screws and slide it downward. With the
screws now in the upper portion of the
slot, and flush with the top of the
Crossmember, tighten the screws. The
Airfoil will face forward when installed.
4. With the Crossmembers inserted
into the Sockets to their marks, drill
completely through the Socket/Cross-
members, centered vertically on the
socket tube 1" in from the open end.
Fasten together.
5. Replace the rack assemblies back
in place on the van roof, and install the
Clamps.
NOTE: Some vans have covers over the
sliding door track, spot welded in place
(
See Figure 7.). If the Clamp will not fit
between the spot welds, place a flat
screwdriver at the restricting weld and
strike it with a hammer to break the
weld. This will give the guard flexibility
to insert the clamp under the rain gut-
ter.
NOTE: Be careful not to thrust the
drill into the vehicle roof. A block of
wood held under the Crossmember
will help avoid this.
6. Place the Ladder Stops on the
Crossmembers centered side to side
up to the ladder side. Mark the Ladder
Stop mounting holes. Drill 5/16" holes.
Fasten the Ladder Stops to the
Crossmembers. (
See Figure 6.)
7. Adjust the Airfoil to eliminate wind
noise by bending it downward to the
following dimensions:
'96 or newer Dodge:
1/2" above roof at center
1-1/4" above roof at each end
'96 or newer Ford:
1/2" above roof at center
1-3/8" above roof at each end
'96 or newer
Chevy GMT600/GMC Savana:
2-1/4" above roof at center
3-3/16" above roof at each end
NOTE: These dimensions are guide-
lines, it may be necessary to adjust
the Airfoil further.

WARNING
Any modification or unintended use of this product shall immediately void all manufacturers warranties.
Manufacturer disclaims all liability for injuries to persons or property resulting from any modification to, or
unintended use of this product.
Ladders must be secured per
ANSI standard A142.2-1990 para-
graph 8.4.4. Place and secure the
ladder so that a rung is against
the ladder stop. Ladder damage
will occur from road shock and
vehicle vibration if the ladder is
not properly secured to the lad-
der rack. Bouncing and side to
side motion of a improperly se-
cured ladder will cause wear and
weaken the ladder. Using a dam-
aged ladder could lead to a
structural collapse and could re-
sult in a serious injury or death.
All WEATHER GUARD® products are
finished with a polyester powder coat-
ing, and it is important to follow these
procedures to get proper adhesion. As
Knaack Manufacturing cannot control
the finishing of the products, the war-
ranty for WEATHER GUARD® prod-
ucts 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 pa-
per.
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.
