Bill, Wrenches I working with a Zep engineer years ago and still dont care to use any of them, wire management is an issue, anything that does get under the module is more difficult to clear, the modules are heavier with the zep product. Rails are now so versatile and cheap, easy to flat and align, place to mount the RSD with a good air gap. I was at a site the installed 24 modules with 2 techs and it was done in 6 + hrs. It was so wavy and loose wiring that it took the next day all day to make it flat and wires picked up.no savings there. But hey that's just me.
