This FRP casing is designed to be used the 12"L X 12"W X 12"H tank 9228. When the tank is used with this casing it can hold up to a 2.2 specific gravity. These casing provide structural support and prevent bulging at the bottom of the tank. FRP casings are required for any media that is has a greater specific gravity then 1.8, or for prolonged elevates temperatures. Casing must be ordered at the same time as tank.
- Specific gravity: 1.8 (2.2 when used with casing)
- Casings are chemical-resistant & maintenance-free
- Covers are included, but casings are sold separately
