Grundorf Utility style road cases are built tough. Each case has multi-layer plywood construction and is glued and stapled for maximum strength. The lid and body of the cases include a special bevel-cut design to "lock" the cases together providing a secure, dust-proof seal. The case is finished with a durable, easy care, carpet finish that will hold up to years of wear-and-tear and heavy duty, all steel hardware assuring this case will withstand years of road life. Grundorf Carpet Series Utility cases are all custom built to fit your gear. No more lugging around a manufacturer's "stock" sized case that dwarf's your gear and takes up way too much room in your vehicle. When you order a custom fit utility road case from Grundorf, you provide the dimensions we provide the fit.
