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 it's 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.

Designed for easy installation in Pull, Push and Double Egress applications, the non-handed track, closer body and dual voltage input makes it easy to specify and install. Common applications are cross corridor and stairwell doors. An auxiliary door stop is required at hold open point. The EHT includes an ANSI/BHMA A156.4 Grade 1 hydraulic door closer and operates as one during the opening and closing cycles.
