Before You Begin
• Read all instructions.
• Be sure to put BH-821 sealant along swage joints and all threads connecting tubes
together. This is to help with water getting into the tubing and causing rust issues.
• During installation onto vehicle, place sealant around all threads entering cargo area and
between the rubber spacer and roof of vehicle to prevent water from leaking into cargo
area.

Step 1 – Determine Distance Between Feet
• On the roof of the
van, determine
desired mounting
locations. Measure
between the
locations. This
distance will
determine the
distance between
the cross bar
assemblies of the
rack. (Transit Roof
Shown)
Step 2 – Assemble Side Channels
• Assemble side channels using the front side
channel and the rear side channel. It does not
madder which side the combination of the two will
go on, just be sure to use the correct combinations.
The sheet metal brackets will align properly when
the correct parts are used. See picture.
• Bolt using two 5/16 carriage bolts, two 5/16 flat
washers and two 5/16 nyloc nuts. Repeat for a total
of two rails assemblies.
**Be sure to apply BH-821 around tube connections**

Step 3 – Assemble Rack
• Assemble the rack as shown below.
• Use the distances measured from step one to approximate where the cross bars should go.
• Do not assemble any part of the rear roller bar assembly.
• Once crossbars are in desired position, bolt caps to crossbars using four 5/16” x 1” carriage
bolts, four 5/16” flat washers and four 5/16” nyloc nuts.
• Snug Tighten, but allow movement. Adjustment will be needed when installing on vehicle.
