The VHD1.0 DOWNFILL ARM is a short, flat pre-angled steel bar that has two pre-fixed apertures at the lower end of the bar to allow different angles of suspension from the enclosure above. The arm is attached to the VHD1.0 down-fill enclosure by means of two apertures that receive the insertion of two D6 QUICK RELEASE PINS. The top of the bar is attached to the bottom of either the VHD2.0 TOP ARM or BASS/VHD2.0 ARM by sliding into the groove and inserting a single D12.6 QUICK RELEASE PIN.
