How to Properly Tie Down Roof Cargo
To prevent damage to the vehicle and/or cargo, as well as overcome updraft concerns, it is absolutely
imperative to tie down the cargo extending past the vehicle windshield and rear window. A bow tie-
down strap is designed to properly secure cargo to the front vehicle bumper undercarriage. The front
strap counteracts air updraft forces, preventing cargo from flying upward or off the vehicle during trav
-
el. To balance the roof cargo load, a stern tie-down strap is also required, which connects the cargo to
the rear bumper undercarriage.
Important Safety Precautions:
• Ensure cargo stored on a vehicle roof does not obstruct driver viewing through the windshield or
rear view mirror
• Do not transport any cargo wider than the vehicle roof
• Tie-down longer cargo with a bow and stern strap
•
Attach bow and stern straps to a solid tie-down point; do not hook to plastic or flimsy bumpers
• Secure roof cargo to the roof rack and side rails
• Check all tie-down connections periodically on travel stops
• Use a cargo net to tie-down all small or loose articles stored on a roof rack
