HI Alan,

I have a UST 589 myself..
The HDX-689 is a custom tower that (with reference to the 589) has one section larger than the 589 lower/lowest section and one section less top section..
Said another way. if you look at the size of the 589 bottom section, you will see that it is ~30 5/8" across one side.. and the TOP section measure ~15"..  
The 689 bottom section measures ~35 5/8" and the TOP section measures 18".
The larger sections of the 689 is what gives it the extra wind load capacity as well as the weight.  The 589 is just under 2500#..   and IF I remember correctly, the 689 weighs over 3500#..

Can't find anything on the UST Web site about an HDX-689 -- only a 589. 
Is yours an older model? A custom model?
