sorry, I noticed the one like in the last message didn't work.
go to
http://www.eastwoodco.com/cgi-bin/s....htm&UID=2002012207355906&FNM=20 and search on "INTERGRIP PANEL CLAMPS " to find them.
they also have many other tools you might find handy.
check out their flanging tools, hole punching tools, also great for patch panel welding.
