Dink, plank, glonk, shank- you hear it constantly as you're driving down the road. Hit a bump and your tools shift around inside the box like a bunch of Mexican Jumping Beans. This Tool Box mat is one of those small things that makes a huge impact. Our non-slip mat with gripping surface will help keep your tools and other items from shifting around and also dampens the impact of bouncing or dropped items. To make a good thing even better we include NoRust by Zerust - Vapor Shield to help prevent rust from forming on your tools. Our Tool box mat is 72 in. x 20 in. and covers the entire bottom of standard Crossover boxes and can also be easily trimmed to fit any toolbox or surface.
