Anodised aluminium rail mount adapter with two M5 screws for 51mm tube

Kupo PSU Rail Mount Adapter for Convi Clamp 51mm

SKU CH-GT0A-V1QDD

Anodized aluminium adapter mounts a power supply on tubes up to 51 mm or flat surfaces via a Convi Clamp using two M5 screws

  • Anodized aluminum resists corrosion for long service life
  • Two M5 set screws lock gear firmly to rails
  • Fits tubes from 5 mm up to 51 mm diameter
  • Works on flat surfaces when paired with Convi Clamp
  • Secure PSU mounting keeps power supply stable during shoots

What It Is

The Kupo PSU Rail Mount Adapter connects a power supply unit to tubes from 5 to 51 mm in diameter or to flat surfaces when paired with a Convi Clamp. It is built from anodized aluminum for corrosion resistance and uses two M5 set screws for a secure attachment to an Arri PSU Rail Mount Adapter. Photographers and videographers who need a dependable, quick-release mounting point for lighting or camera rigs will find it useful.

Practical Limits

The adapter only works with tubes that fall within the 5 to 51 mm diameter range and requires a Convi Clamp for flat-surface mounting. It must be combined with an Arri PSU Rail Mount Adapter to function, so buyers without that companion piece cannot use it. The two M5 screws provide the sole locking mechanism; no other fastening method is included or supported.

Deciding Spec

The 51 mm maximum tube diameter is the single figure that determines whether this adapter fits your existing rig. If your rails or bars are larger, the adapter will not clamp securely and a different mounting solution is required.

Questions about this item

Which diameter tube does the Kupo PSU Rail Mount Adapter support up to?

The adapter fits any tube from 5 mm up to 51 mm in diameter when used with the Convi Clamp.

What real-world stability does the anodized aluminium construction give when a power supply is mounted?

Anodized aluminium resists corrosion and wear while the two M5 set screws lock the adapter firmly to the rail, preventing shift during a shoot.

How does the M5 screw interface limit the way I can attach the adapter?

Two precision M5 set screws are the only mounting points, so the adapter must be secured to a compatible Arri PSU rail or similar M5-tapped surface.
