Bob,
Just checked a TOWER listing, and they have the J'Tec stands. On the catalog page, one is the LXR588, which I like. The clamp pads are held on with countersunk, flat head bolts. No stub threads, nuts or washers to get in the way of a muffler, if you're using one. Nuts are tightened from underneath.
Been using one for the past several years, and it stands up better than the older J'Tec/Tatone type stands...
