You can kinda sorta see it here.

You probably can't afford a nice workbench after buying all of
those parallel clamps at ~$40 each... ;o)

I got the Cabinet Master clamps for about $17 each so I loaded up.. This
was several years ago when the screw clamp end was made from aluminum.
Jorgensen switched to cast iron when the aluminum failed. With a lifetime
guarantee all 10 clamp ends were replaced for free. No problems sense.


Me too from Woodcraft on a special. bought 4 of each size.
Mine have not failed, didn't know the reason for the black ones?
What caused the aluminum to fail?
Did yours fail or you were just pre-emptive?



They were failing on one at a time and they replaced them one by one for
the first three. Next two failed and they asked how many more aluminum ones
that I had and they decided to replace the rest and be done with it.

They replaced 2 iron ones because of a gritty feel when you tightened the
clamp down. I later discovered that a drop of oil internally where the
swivel pad is attached to the screw makes them work like new again.
