While Posiflex takes pride in designing and delivering products that stand up to the harshest of environments, Posiflex terminals are not fire proof, water proof or shock proof. Not all systems provide the same level of debris and spill resistance. Only Posiflex models KS7215, KS7217 and KS7515 (call for most current models) are spill and dust resistive. Posiflex makes no such claims for any other terminals or systems in the product line. Use deemed to be excessive, abusive or improper will void the warranty.
