Children are especially prone to squeeze their fingers in glass swinging doors. This safety door prevents that, because it „gives“. Thus part of the door leaf is mounted separately over an additional axis of rotation. This 49 mm-wide strip of glass moves in the opposite direction in case of resistance and prevents injury. For this safety feature to operate well in the long run, the material must have high abrasion resistance. These requirements are easily met by the built-in iglidur® plain bearings.
