We installed them under the drawer and on each side of this drawer. It now opens up smoothly and VERY EASILY. We did have two of them that were not holding together, and when I reach out to the seller -- MAD ORGANIZER and Mr. Jonathan - THEY responded not even within a 24 hour period offering to sending replacements!!!!!!
In this world of current chaos and corporate greed - I AM SO GRATEFUL for such high quality customer service!!!!
Thank you MAD ORGANIZER and Mr. Jonathan for being so PROACTIVE. I wish you a safe and healthy rest of the year.
