but the lever system never seemed to hold the rubber belt.
I tried a few things to help the lever situation and never had faith that it would hold me 20' feet high.
I don't have any idea how or why the cam(lever) system wouldn't work for you. I've owned 3 LW sitnclimbs.........no problems whatsoever and once the cams are closed, they stay closed. Safest climbing stand on the market IMO. I'll be owning another one before the season.
