Arrived incomplete.  Contacted company and was told new part on the way.  Was emailed a note from company saying part was delivered by USPS with a tracking number that was not valid.  So, instead of Wayfair sending me a new gate that is complete along with a tracking number to send incomplete one back, they are now contacting the same Chinese company that jerked me around for over a week to get the "part."  That should be helpful.  Puppy will be full-grown by the time this is solved.  Boooooo Wayfair.  Giant fail!
