The outer slot wall is extended as the housing wall and at its end forms a reception slot for receiving a housing rear wall (22). The inner slot wall (23) has a vertically protruding fixing web (19), for the formation of the fixing frame. The module inserts or housings (30) are secured to this fixing frame. The T slot (16) is formed by slot webs (17, 18) provided at the outer and inner slot walls (20, 23), aligned opposite each other. USE/ADVANTAGE - Main entrance of apartment block or door entryphone.
