This Better Built box is one of our best sellers. This box has the popular single lid, low profile design allowing you more visibility out of the back window of your truck. And it's made tough with a double rib lid brace to add rigidity to the lid, self adjusting strikers that won't need adjustment with long term use, locking stainless steel paddle handle locks, and a silver diamond plate construction that will stay great looking for years. This box features auto-lift self-rising gas shocks for easy single hand opening and the lid opens to near 90 degrees to allow you access to all your gear. Also has an plastic interior sliding tray for your smaller gear. Fits most full size trucks. Install available for an additional $40 for clamp mount or $80 for drill and bolt mount.
