I cleaned out an old radiator repair shop and these heavy duty 2" Stuart c clamps were bolted to some aluminum fixtures. So i removed them and gave them a soaking in oil and they worked again. Never saw any this heavy duty for their size but i have 8 of them. Going to take them to work and put them back to use...Bob

Nice cleanup find!

Good job.  Especially putting back to work. Thumbs Up

Those are some serious clamps!
Nice job putting them back to work.

Nice find

Irresistible C clamps.  I found a couple of smaller ones last summer, and just had to have them.  Good job, and nothing is more musical to my ears than "returned to service."  Good on you.

those are nice!

Well i took them to work today and they just fit in the little box i had. One guy said those are really old i said i know the place was 50 years old i got them from...Bob
