The least favourable point of the door was chosen for the attenuation test. ETS-Lindgren’s Euroshield brand door unit consists of frame and door for nominal 800 x 2000 mm and 1000 x 2000 mm, as standard sizes, mm clear opening together with internal type recessed hardware and two special hinges.

The patented hinges allow the final closing movement to be parallel to the door frame and also permit a normal circular trajectory when the door is opened wide. RF seal is obtained by cam followers at both edges of the door. The door has two recessed contact fingers. The door is easy to handle because the opening and closing mechanism is equipped with bearings. The door can also be designed for welded installation to the shielded enclosure. The door can be equipped with pneumatic operating system for lighter operation. In this case the door must be opened manually; the operation system just releases/closes the RF-tight locking.
