Designed for marine environments, these chests are made of fiberglass and have stainless steel hardware, so no parts will rust or corrode, even in salt water. They’re stronger than aluminum chests and won’t conduct electricity or heat. A UV coating protects these chests from sun damage, so you can leave them outdoors for long periods of time too. Gas springs help you open and close the lid smoothly. Use a padlock (not included) to secure stored items.
