These guys have a LOT of info on the E-Locker. I just went through them last week for my e-locker install - and they are the most helpful people I've talked to on the phone in a while. I'd call 'em if you can. http://www.inchwormgear.com/store/product_info.php?cPath=25&products_id=37

I don't know the answer to your question though, good luck!
