Ultimate Support TBR-130-2 13in Tribar Support Arms - Reinforced Tier

Our review of the Ultimate Support TBR-130-2 finds it to be a focused solution for keyboard players who need a dependable, mid-height tier without replacing their whole stand. The bottom line: these 13in tribar support arms deliver the reinforced strength and straightforward compatibility expected for use with the APEX AX-48 Pro when paired with the CMP-485 Super Clamp (sold separately). They are best for musicians who already own the AX-48 Pro or plan to upgrade that stand with an additional tier while keeping load and tier count within recommended limits.

Key Features

• Reinforced Tier Support Arms: Built for extraordinary strength so the arms can safely hold mid- to small-sized keyboards with confidence.
• Super Clamp Compatibility: Designed to hook into the CMP-485 Super Clamp so users can add a secure tier when the clamp is fitted to their stand.
• APEX AX-48 Pro Compatibility: Specifically sized to form an APEX tier on the AX-48 Pro keyboard stand for a seamless physical fit and alignment.
• 13in Depth: The 13in tribar depth makes these arms well suited to mid- and smaller keyboards where deeper 18in arms would be unnecessary.
• High Load Allowance: Intended to be used within the system limit of 250 lbs total and with no more than two tiers to maintain stability and safety.

Who It's For

These tribar arms are ideal for gigging keyboardists, home studio owners, and rehearsal spaces that use the APEX AX-48 Pro and want to add a sturdy second tier without replacing the stand. They suit owners of mid-sized keyboards and synths who value a compact tier that keeps controls and keys accessible.

Players who need extremely deep or heavy-duty tiers for large workstations should consider the larger TBR-180 18in arms or a purpose-built stand for heavier loads. Also, buyers who do not already own or plan to use the CMP-485 Super Clamp should note the clamp is required and sold separately.

Pros & Cons

Pros

• Reinforced construction provides a reassuring level of strength and stability for mid-sized keyboards.
• Direct compatibility with the APEX AX-48 Pro makes installation straightforward for that stand model.
• 13in depth keeps the tier compact and ideal for ergonomic positioning of smaller instruments.

Cons

• Requires the CMP-485 Super Clamp (sold separately), so total cost rises if the clamp is not already owned.
• Intended for mid- to small-sized keyboards only; larger instruments benefit from the 18in option.
