The Roll N Lock lid locks to the truck bed for added security and retracts all the way back to the truck cab, giving you full access to the truck bed.
In addition, the lid can be either: Fully closed, open one third, open two thirds, or fully open.
The Roll N Lock is also weather proof and improves fuel consumption by reducing the amount of drag caused from an open truck bed.
With a sophisticated Black finish that will not tarnish over time, class leading security is also achieved via twin locking points that prevent the truck's tailgate from been opened when the roll top is locked - quality and peace of mind assured.
