Quotewonder why only certain ones have them.

Because they are to be sold to users who don't know the correct way to use an adjustable.

>the correct way to use an adjustable.

The small end is the handle, the large end is the hammer head..right?

You got it!!!

Anybody else have a Poly-Lock?

Lewill - That is an interesting looking wrench.  Is there any information you could share re: "poly-lock"?

Plomb me up Scotty...................




Hard to tell in my poor pic, but the hanger holes are also box end wrenches on the adjustables.




(The 4 inch was not in this pic for some reason.  Will try to find it, and capture a pic with the 20 inch (not shown either) for fun.)

Oily,
The circle AZ Craftsman was patented and made by JH Williams. The pin through the thumb screw locks the thumb screw when you push it upward. It unlocks when you push it back down. I have a couple of them, an 8 and a 15inch. I posted them a few months back. Below is the Williams Catalog page from 1962 or 63.

Posted in the Thorsen thread, but here also for the sake of grouping.

Thorsen 10" adjustable; model AW-10.  Marked "AW-10 THORSEN" / "FORGED ALLOY STEEL USA".

Found the 4" Plomb adjustable.  The 20" Plomb is a 720 S .  Jaws open to 2-1/2".

Excellent!

8" Urrea Model 708 - hecho en Mexico - I understand there is some connection to Proto where I should go educate myself on the details.
