The trellis is fine.  I returned it because of the very poor installation by Kevin, the Handy “expert and vetted” installer that came to install.  After he left I jiggled the trellis and the screw literally came out.  I called him using the phone number supplied to protect his privacy.  He assured me he would come back “to make it right”.   Haven’t heard from him since.  The Handy installers are not vetted.  They pick the projects that sound easy whether or not they have the experience necessary.  I’ll return the trellis.  Can’t believe Wayfair is associated with such a scam.
