FPPI's Back Box for Fire Alarm Bells is made from high impact ABS thermoplastic. ABS is known for its strength and rigidity and has superior electrical insulation properties as compared to PVC, Styrene or other plastics. ABS can also be used in a wide range of temperatures from -13° F (-25° C) and 140° F (60° C). ABS is resistant to the elements that would normally cause corrosion in a similar back box made from cast aluminum with a painted finish.
