It's easy to trim the ribs to get the right fit when needed.
Our decking table set is very old so I think the holes in the bottom of the legs are not up to modern standards but it was easy and quick to cut out a few side and end ribs and it still is very tight fit.
Pros
Commonly used office/patio furniture, chair rails, furniture legs, wrought iron, appliances, exercise equipment, pipe stands, appliances, trailers, shelving or anything that requires a clean look.
