I bought these pads for some old pipe clamps that were not Jorgensen clamps just to see if they would work. To my surprise they worked on all the pipe clamps in my shop (24 different size and types). A lot of the home improvement and hardware stores within 50 miles of my shop (in Kentucky)  do NOT stock these pads. The price was fair and these pads do a great job protecting the wood surfaces. I highly reccommend them to any one using pipe clamps!
