To install:
1. Insert a tie-down loop
assembly until it is flush with
the truck bed wall.
2. Turn the tie-down loop
clockwise to tighten. The
tie-down will be hard to turn
until the toggle moves past the
installation point on the toggle
guide.
3. Fasten the tie-down firmly by
hand only. Do not use tools.
To remove:
1. Remove the tie-down loop
completely by turning
counterclockwise while
holding the backing plate
against the truck bed wall.
2. Pull the backing plate away
from the truck bed wall until a
click is heard. This locks the
toggle into position on the
toggle guide.
3. Push the backing plate against
the truck bed wall. This allows
the toggle nut to spin.
4. Remove the backing plate,
toggle guide, and toggle nut
from the truck bed wall
completely.
5. Reinstall the tie-down loop
through the backing plate into
the toggle nut for reuse.
