I contacted Irwin industrial tools to get replacement parts for some clamps.
The clamps have always performed better than the knock off clamps sold by Harbor Freight, so I just needed replacement jaw pads, which get a lot of abuse when you're working with grinders, and power tools.
The customer service guy asked me to send a picture of the clamps so he'll know the type and size, so he can send the proper parts. I snapped a few pics and emailed them.
About 10 days later I get a package with several replacement clamps not just the pads.
He said several clamps needed to be replaced, so he sent new ones, and charged me NOTHING.
Needless to say I was impressed with the rep, as well as a company that stands behind their products.
I love my Irwin mechanical carpenter pencils, but there hard to get because there always sold out at fleet farm..
