This system can be used to convert any door to be opened automatically at the touch of a button. This is particularly beneficial for people with reduced mobility. For conversion, a strip is glued to the button end of the door leaf. The automatic door opener is set on this strip. The main components of the system are a drylin® W double rail and the matching drylin® W linear plain bearing. In this application the drylin® W products stand out by their quietness and smoothness as well as resistance against dirt and dust.
