Tool box Tonneau Covers

If you have an over the rail tool box installed on your truck, you know that regular tonneau covers won’t fit. You don’t need to sacrifice protection to use your tool box though - specially compatible tool box tonneau covers are available, sized to work with your tool box! You can protect the cargo in your bed without sacrificing the usability of your tool box. Our covers are custom-fit to your specific year, make, and model, and work with most traditional toolboxes that occupy 20-21” of bed space. Alternatively, some come ready with custom under-tonneau or integrated tool boxes included. Still have questions? Call our product experts at (800) 874-8888 and we will help pick the right toolbox tonneau cover for you!

Extang Toolbox Tonneau Cover

Good but

This is a nice tonneau cover but the seal at the toolbox holds the rails up in the front and the seals on the side don't touch the bed of the truck in the front the instructions are not for a truck with a tool box so there mounts don't actually fit were they say to put them I bought extra thick weatherstripping and all is good but should have come with thicker seals to begin with View more reviews...

Extang Trifecta 2.0 Toolbox Tonneau Cover

Best cover when using a toolbox

my second purchase of this cover - had it on my 2014 and now on my 2019. Easy to use and install. Wish it was easier to put somewhere in the truck when not being used, but it's too long for the back seat, but it can be put in the bed and strapped if moving something. View more reviews...
