Ultimate Support CMP-485

The Ultimate Support CMP-485 is a hardware accessory used in the Ultimate Support Apex keyboard stand system.

What it is

The CMP-485 is a super clamp / column clamp that attaches to the central column of Apex-style keyboard stands (like the AX-48 series). It’s used to mount additional “tiers” for keyboards.

What it does

• Connects to two Tri-Bar arms (TBR-130 or TBR-180)
• Creates one extra keyboard tier (platform level) on an Apex stand
• Allows you to expand from 1 keyboard setup to 2 or 3 tiers depending on configuration

Compatibility

Works with:

• Ultimate Support AX-48 Pro
• AX-48 Pro Plus
• DX-48 series
• Other Apex column stands

Key specs

• Load support (per tier): ~125 lbs (with tribars)
• Total system capacity: up to ~250 lbs (system dependent)
• Lightweight metal clamp (~0.8 lb)
• Height-adjustable fitting

Important note

• Tribars are NOT included (you must buy TBR-130 or TBR-180 separately)
• The CMP-485 is basically the “connector piece” that makes extra tiers possible

Simple explanation

Think of it like this:

• Stand = vertical pole
• Tribars = arms holding your keyboard
• CMP-485 = the hub/clamp that locks the arms onto the pole to create a full tier
