Spiral duct hanger LRBN / LRB

Fastening components - Spiral duct hanger LRB and LRBN

The fischer ceiling hanger LRB for light loads and the LRBN for heavy loads are fixing elements for reliable acoustic decoupling between spiral pipes and the substrate. The multiple holes enable mounting with drill screws or rivets to the spiral pipe, which saves time. A through-hole on the sound absorption element enables pipe height adjustment during and after the installation.
