The fischer cantilever arms ALK enable the cost-effective fixing of single conduits and pipeline routes along walls as second base elements with the mounting channel profile FLS. Thanks to the slots at 90° to each other, the cantilevers can be easily adjusted. The ALK does not need to be cut to size because fischer offers standard lengths from 200 to 600 mm. The zinc-plated version is suitable for installation in buildings. The fire inspection report as per MLAR / EN1363-1 of the ALK 37 provides added safety.
