Multilayer sheets of an acrylonitrile-butadiene-styrene resin layer and a relatively high rubber acrylonitrile-butadiene-styrene resin layer are provided which are thermoformable. The multilayer sheets exhibit resistance to halogenated blowing agents which escape from foamed-in-place insulation. The multilayer sheets can be thermoformed to provide equipment liners such as refrigerator liners, dishwasher liners, car interior panels, and appliance housings.

The invention provides an easily transportable, general purpose box which may be carried about by hand and then anchored to rails and locked in place. Once the lid is locked on the box, no one without a key can move the box from the anchor rails. The invention is primarily intended as a portable trunk for mounting on a truck; however, it may be used anytime that a box is to be mounted on a chassis, such as a toolbox mounted on a wheeled dolly, a toolroom shelf, or the like, for example.
