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.

12

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.

Light Loads
