31128 by Dometic is a black surface-mount housing designed for compatible combination propane (LP) gas and carbon monoxide (CO) detectors in recreational vehicles. It allows the detector to be installed on a suitable surface when flush mounting is not practical. The housing attaches to the mounting surface with screws, and the compatible detector is secured inside the box. This accessory is the mounting box only; the gas and carbon monoxide detector is sold separately. Verify compatibility with your existing detector before ordering.
