TEST-74 profile is a mounting strip for STOS profile. After TEST-74 and STOS profiles have been mounted, we obtain a groove inside high enough to route 6 mm Fi cables in it. STOS profile is attached to TEST-74 strip with TEKNIK clips, arranged in pairs. The pairs of the clips should be applied every 20 cm.TEST-74 has its own end cap, which nicely complements the shape of STOS end cap. Mounting instructionsTEST-74 strip is mounted using suitable screws. The location of the drilling of holes for screws is marked by the groove inside the profile.The mounting surface for TEST-74 should be even. If there is some major roughness of the surface, mounting screws should be located in the places of profile-surface adhesion (bumps).
