Jim,
I have a US Tower HDX-589 and also use their standoffs. I like the
idea of yours to use a 90 degree PVC sweep elbow on the top standoff.
May do this myself.
Do you have a picture showing this top standoff ? What size elbow did
you use ?
Mickey,
I found another provider of tower standoffs for info.
His standoffs use u-bolts for connection to the tower legs.
