I have three umbrella and tables in my yard. One blew out of the table and a wooden rib broke. I was thrilled to find these frames. So I bought three so they would match. They look wonderful but the frames are a bit too long for the correct and too short for the next hole. So I tried to insert the rib using the correct hole but I broke one of the small ribs at the top. I did save it by using a zip tie to secure it and it has worked so far. Because the next hole down was too far and the canopy sagged I was creative and put some wadded cup newspaper into each canopy holes that the ribs go into. Now they look great and do not sag. My old frames were the same dimensions but somehow they weren't quite right but I made it work and I love them.
