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.

Baby
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.

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

Stud
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”

Receiver
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.
