This type of blade offers fast and easy assembly and better vandalism-resistance than the standard aluminium CL S. The blades can only be used for riveting or screw-fixing to an existing full back structure (wall, metal sheeting, …).
The extruded profiles are only available in types L.033 or L.050. They consist of 3 to 4 blades extruded together. The profiles are available as punched (L.033.07 / L.0 50.07) or unpunched (L.033.05 / L.050.05) versions. The block blades can be used in conjunction with the standard blades.
