CAUTION:
These loops, when used, are under a lot of force.
Always pull the vehicle straight out. Never pull
on the loops at a sideways angle. The loops could
break off and you or others could be injured
from the chain or cable snapping back.
NOTICE:
Never use the recovery loops to tow the vehicle.
Your vehicle could be damaged and it would not
be covered by warranty.
