The arm for 6 or 12 lights Ref. BR-12 is specially designed to hug the tube and thus avoid damaging it with the pressure of the screw (the screw does not directly touch the tube, thus avoiding friction). It is valid for towers and loudspeaker stands with Ø 35 mm terminal. The crossbar includes tools for mounting the spotlights, both in its lower part and in the upper part. The maximum distributed load is 85 kg.
