Our fiberglass injection well covers, commonly referred to as Frost Boxes, are engineered to provide reliable protection and insulation in a variety of environments. Each box is fully insulated to safeguard wells and equipment against freezing temperatures, while the rugged fiberglass construction ensures long-lasting durability in both residential and commercial applications.

Every unit is designed with lift tabs at the base for easy handling and secure placement, along with a removable top access cover that allows for quick inspections or maintenance without the need to move the entire box. For added convenience and security, the covers include integrated tabs that are compatible with most bungee cords, making it simple to fasten the lid tightly during transport or to secure it against strong winds and harsh climates.

In addition to their strength and insulation, these Frost Boxes are intentionally built as conspicuous structures—a visible safeguard that helps protect sensitive field setups from potential damage caused by farming operations or heavy equipment passing through. By standing out clearly in the field, they reduce the risk of accidental contact, ensuring equipment stays intact and functioning properly.

Built with functionality, visibility, and versatility in mind, these Frost Boxes are ideal for protecting injection wells, utilities, and other critical systems where insulation, accessibility, and field safety are equally important. Whether in agricultural, industrial, or municipal settings, they deliver dependable year-round performance.
