Forgot to mention my experience with one of my Jorgensen/Pony pipe clamps.
One has had problems with the clutch plates over the years and finally the last one broke.
Their web site has the clamp model numbers and parts lists. When all the parts had a price but the clutch plates I sent an email to the contact listed.
The response was if they are ordered the shipping is too high and they would just send replacements in the mail.
They arrived quickly. I sent an email to let them know they arrived and thanked them for the quick service.
So there is another company out their with service that deserves a mention.
Somewhere some other makers pipe clamp set was purchased. They may have been a couple dollars less. They do not have any marking on them. If a replacement part is ever needed, those couple of dollars saved won't look so good then.
