​ETS-Lindgren's Single Knife Edge (SKE) Door with Semi-Automatic Electo-Latch offers superior knife edge door reliability, performance and longevity. The SKE Door (S201) features a precision-formed knife edge, a proven Recessed Contact Mechanism (RCM), and an Automatic Latching with Assisted Door Closing to deliver reliable shielding, exceptional performance, and easy maintenance.

The emergency release system consists of two handles located at each side of the door, which when pulled to a horizontal position, can be removed to enable the door to be opened in the event of a power outage.

The Series 201 personnel doors have three precision-machined aluminum hinges.  Each is fitted with adjustable thrust bearings that enable the door leaf to be accurately adjusted within the frame and to compensate for varying loads conditions.
