Magnetic Socket Holders/Bars

Does any one know of a company that makes magnetic socket bars WITHOUT posts? The Mechanics Time Saver ones are too deep for serpentine belt tool sockets and the sockets have a male drive that fits into the handle so post style will not work. I have found a few generic magnetic bars that are made to mount on the wall but they are excessively heavy.

I have seen some magnetic socket bars with little rubber balls to insert into the drive of the socket (sized to fit the various drive sizes). Don't know if this will help you or not.
