James – we have a spool at the top of each of our 6 drums which puts the top head cover at about waist high. It works very well. The only issue we had recently was that the spiral wound gasket in one of the drums started to unwind. We pulled it and installed a CGI (center guard insert) type of spiral wound. In addition, we also have the captivated nuts with the self centering bolts and they also work very well.
