Hex Grip Head

The Hex Grip Head is identical to the 2-1/2” Grip Head with Big Handle – Black (KG203111) but instead of being mounted to a baby 5/8″ (16 mm) receiver, it’s mounted to a hexagonal stud designed exclusively to fit the Convi Clamp or Super Viser System. The ability to mount a grip arm to one of these incredibly versatile clamps gives you the ultimate flexibility in rigging possibilities. You can mount a modifier such as a scrim or silk on the same stand that the light fixture is mounted to.

This is a shot of Profoto 7a 2400 Generator suspended from a Hex “J” Hook and Convi Clamp from a C-Stand Riser Section. They are especially popular for battery operated strobe packs on wheeled stands. Not only do they get your electrics off the ground on location when the ground maybe wet, but they also provide some extra weight for stability to save the need for a sandbag.

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.
