351 EHT

The EHT Series of Electromechanical Closer-Holder Release Devices is designed to hold open fire rated doors until power is interrupted by a fire alarm condition or remote release switch. With its rugged track design, the 351 EHT is suitable for multiple manual operations. It is also applicable for non-rated doors such as offices or conference rooms, where the convenience of an electrically controlled closer-holder device may be desirable.
