Hi All - Wondering if I can throw myself at the mercy of the club, and see if anyone has a set of heavy duty glass suction cup handles that I can borrow/rent? I need to move a pretty heavy glass tank down some stairs, and then back up some some stairs, and it seems these can make the job quite a bit easier. I'm in San Francisco, but will drive a little bit if needed. As an aside, seems like a good set of four of these would be a great addition to club's loaner equipment list. Thanks!
