Maintain an open door position through an electrically controlled hold-open point with the Security Door Controls EDH-SFL configuration. Electric door holders are used where doors need to remain open during normal operation but release when their hold-open power is interrupted. This supports controlled closure as part of a door-control or life-safety sequence. EH2024120A is specified with 24 VAC/DC and 120 VAC electrical operation and a chrome finish. That voltage coverage is important when matching the holder to the available branch or control-circuit power at the opening. The EDH-SFL surface/flush format provides a designated electric hold-open hardware option for an opening rather than a locking device. Use this electric door holder at openings where a held-open door must be released by the controlling circuit. Confirm the site’s electrical supply, door hardware arrangement, mounting location, and control sequence before installation. The chrome finish suits installations that require a finished visible hardware surface while retaining the functional purpose of electrically controlled door retention and release.
