The Mighty & Versatile Convi Clamp

Convi Clamp Trio


The Convi Clamp is more than just an amazing clamp, it’s the foundation of an entire grip system. It features a hexagonal receiver that accepts dozens of Convi accessories from a simple stud to the versatile Max Arm to mount almost any light fixture, camera or accessory. The hex receiver features a spring locking safety system to ensure that the Convi accessory won’t separate from the clamp if the locking screw loosens unexpectedly. It also comes with a saddle to securely mount it on flat surfaces.

The Convi Clamp has been a staple in the grip industry for many years and its style, depending upon the manufacturer it is also called a Mafer or Super Clamp.


While there may be other manufacturers with a similar style of clamp, Kupo’s Convi Clamp has some distinct advantages. Here are some of the reasons that make our Convi Clamps stand above the crowd:

  • The all-metal Convi Clamp is made from a strong lightweight alloy.
  • The Convi Clamps are certified with a TÜV Rheinland safety rating up to 44 lbs (20 Kg) making it 25% stronger than the competition.
  • All three Convi Clamp styles come clad in a silver alloy or stealthy black powder coated finish.
  • The Adjustable Handle model’s handle can be quickly repositioned when in tight spaces.
