Do not pay for installation - Wayfair is incapable of communicating the specific type of install required for a handrail. They categorize it as “furniture assembly”. My Wayfair  Angi pro no-showed on the first date that they scheduled and the rescheduled pro cancelled last minute once he learned the specific install he had accepted. I rearranged my work schedule to be home for 3 hours two different days in the same week FOR NOTHING!!
