The HQ-218 is offered in two exposure ratings-“covered exposure” (CX) for applications where cabinets are covered or protected, and “direct exposure” (DX) where cabinets are unprotected and directly exposed to the environment. The CX versions are protected with a thick ISO-flex coating on both the exterior and interior surfaces. The DX versions augment the protection rating by employing a fiberglass exterior and a gel coat sealed interior. Both versions are rated IP54.
