Cal-Van Converter cropped

Most socket sets include a downsize adapter for driving 3/8″ sockets from a 1/2″ ratchet, but they never include an upsize adapter. Cal-Van helps us out with this tremendously clever double-ended adapter that can convert in either direction! Check out the deceptively simple mechanism after the jump.
To drive a small socket with a large ratchet, push the central bar one way:


And to drive a large socket with a small ratchet, just push the central bar through the other way:


Thanks to the knurled body, you can spin it with your fingers, in either configuration. It also functions as a short extension, but its length could make it awkward in tight spaces. But, hey, if things are that tight, just go get the right ratchet!

Cal-Van makes one version for 1/4″ and 3/8″ and another for 3/8″ and 1/2″ drives. This little piece of American ingenuity will set you back about $8, unless you have to pay shipping. Try your local Sears.

  1. I saw that just yesterday and wondered why it was so long.

    I don’t like to use up-converters for fear that I’ll overtorque and damage my ratchets. Am I just being over protective?

  2. If you’re using enough torque to damage a ratchet with an upsize adapter, it’s also enough torque to damage the ratchet with a regular socket in its normal drive size. Smaller ratchets have shorter handles, and I trust my hand to tell me when I’m exerting too much force.
