C-47 aka clothespin

The C47

The C47 is incredibly cheap and extremely useful, as is a wide array of clamps, in the machine vision laboratory.  The C47 appears identical to an ordinary wooden clothespin.  (I’ll let you in on a secret:  they’re the same.)

For some reason, lost to memory, the clothespin was renamed C47 in the movie industry.  Gaffers and grips carry a dozen or so with them wherever they go.  They’re just so versatile.

The cost of a package of clothespins – sorry, C47s – is ridiculously inexpensive; almost below the effort for petty cash reimbursement.  Try the local dollar store when you’re nearby.
