We took our toughest mobile tool chest and made it tougher. Now featuring an aluminum rail slide system, each tray slides out into a secure position for easy access of your tools and can be effortlessly removed for repositioning or cleaning. The robust design has been tested for water submersion, extreme temperatures, and drop tested from 5 feet. This case can take a beating while keeping your tools intact. Plus, the extendable trolley handle and rough terrain wheels take the strain off of transport.
