The UWS Utility Chest Box is a beast when it comes to both security & protection of your valuable payload. The RidgeCore lid has a patented rigid foam core that adds extra structural strength, preventing warping and bending. The rigid foam core is done by layering a sturdy foam core between two sheets of aluminum. A MicroSeal gasket is used inside the lid to form a tight seal when closed, keeping moisture and debris away from your cargo. The lid self opens to almost 90 degrees for convenient access & loading. Lock handles for are built to last and offer not just security - but the stainless - steel lock handles are corrosion resistant. The connecting rod included means the chest box can be accessed from either side. If you are looking for a well built chest, the UWS Utility Chest fits that need!
