The Baby 5/8″ Snap-In Pin mounted in a Convi Clamp with Adjustable Handle. The advantage of the hex pin is that it won’t rotate in the clamp’s receiver. Also there is a safety mechanism built into the Convi Clamp, if the set-screw ever comes loose, the pin can’t be separated from the clamp unless the safety button is pressed down first.

The same Baby 5/8″ Snap-In Pin mounted to Convi Clamp with Adjustable Handle clamped around the riser of a C-Stand. This gives us the freedom to mount our Profoto head or any other light fixture with a baby receiver anywhere we’d like on the riser section. This is perfect if you want an ultra-low mounting position and your stand is of normal height or is too tall.


Not only are they designed for our Convi family of clamps, but also for our Super Viser Clamps with the same hex receiver that also feature the hex receiver. If you ever needed a clamp with a baby pin on both ends, the Super Viser with a Baby 5/8″ Snap-In Pin would be a perfect solution.

Baby vs. Junior

When it comes to grip equipment, one has to be familiar with industry standard sizes and vocabulary. Whenever you want to join two pieces of equipment, you have only two main sizes to deal with: Baby & Junior. Then you have to know whether it is male or female.

A “baby” refers to any stud (male) or receiver (female) that’s 5/8″ (16mm) in diameter. This is an industry standard and all modern photographic light stands use this standard.

A “junior” refers to anything that’s 1 – 1/8″ (28mm) in diameter. The increased diameter gives this connection a higher load capacity.

The word “stud” has many definitions, however for image professionals, one is usually referring to definitions 3 & 4.

  1. A guy who is popular with the ladies.
  2. A male animal desirable for breeding.
  3. Any of various infixed pieces (as a rod or pin) projecting from a machine and serving chiefly as a support or axis.
  4. Also known as a “pin”, “spud” or “spigot”

This is female counterpart that receives a stud. Generally it is a metal tube that has some type of locking screw to secure it in place. The receiver is also sometimes known as a socket.

So the next time somebody asks for a “baby stud”, don’t look around for a toddler with a leather jacket, a tricked out tricycle and sunglasses.
