• Works with a CMP-485 Super Clamp (sold separately)
• Used to create an additional tier (second or third level) on APEX column-style stands

Key specs

• Arm length: 13 in (330 mm)
• Sold as: pair (2 arms)
• Load capacity: about 125 lbs per arm (≈250 lbs total per tier system) when used correctly
• Designed for mid-size to small keyboards / synths

• Ultimate Support AX-48 Pro
• Ultimate Support AX-48 Plus
• Other APEX column stands using CMP-485 clamps

What it’s used for
