Elbow screw joint system

A method for assembling of an elbow screw joint system comprising a guide body with a guide recess and an outlet recess arranged at an angle to the guide recess, an insert and a cover, wherein the insert comprises at least one rotatable guide section which can be disposed at least partly in an interior of the guide body, the method comprising:

• inserting at least one long line component through the insert such that the at least one long line component is guided into the guide recess of the guide body and emerges from the outlet recess which is arranged at the angle to the guide recess in the guide body,
• inserting the at least the rotatable guide section into the guide recess of the guide body,
• rotating the guide body about a longitudinal axis of the guide recess such that at least one recess of the guide section is aligned to the outlet recess of the guide body, and
• screwing of the cover over a head side of the guide body to a threading of the guide section and locking an alignment of the guide body.
