EASY USE OF TRUCK BED
Tarp may be rolled up and secured with buckle
straps for bulk hauling. For more access, tarp can
also be removed completely by loosening T-knobs.

Seal the tonno by pressing the
velcro© fastening strips from
the cab end and press all the
way back.
Before using any commercial car wash, push down
both sides of the Velcro© strips. This will reduce the
possibility of water entering the truck bed.
Over time, the velcro might develop a fuzzy appearance.
This is normal and will increase the holding strength.
Built in Tie-downs
Clamp tie-downs for light to moderate loads
(100 lbs max.) can be used whether tonno is in
place or not.
