• no drillings for fixing of base-extrusion required, because of fixation by hammer-head-bolts
• base-extrusion can be used for water-drainage
• good twisting properties due to high flexibility
• comfortable installation of thermal separations
• standard-finish as stated above; further finishes on demand
• cap screw also with countersunk available (e. g. for facades)
