I measured my daughter’s island cabinet openings and ordered 2 sets of these double drawers for her as a Christmas gift. This is the morning of December 26 and my son-in-law has already installed them for her! Easy installation!  She can now see and access EVERYTHING in her island easily…these inserts were a good purchase. My son-in-law works for a high-end builder/remodeler and he was impressed. He said some units come completely unassembled and take his crews so much time before they can even start to install. These were a pleasure to install!  You may get more sales from his recommendations! Thanks for a great product and also smooth ordering and delivery.
