Riser clamps...

Can't find any. I really only went to Lowes. Does anyone know if Home Depot carries them?

I did a google search for plumbing supply stores in my area and came up empty. Maybe the yellow pages is better.

Where did everyone else get them? thanks.

found stores in yellow pages....

Unless anyone knows that ********* has them, looks like I found some supply stores not too far away.

Some don't look like they have the 4" ones, though.
