SDC’s S4000RE is a Low-Profile, High Value Electrified Grade 1 Exit Device with stainless steel construction. Not all exterior doors have adequate overhang protection, exposing them to weather and corrosion. The S4000ER is corrosion resistant and comes with Motorized Latch Retraction and Request-To-Exit standard at no charge - making it more cost-effective than competitive exit devices requiring add-on options. Application is as easy as Install – Power – Done.
