I ordered these lids because I assumed they would be identical to the lids I bought from Menards in Gillette, Wyoming in 2015. These lids snap onto the bucket, making the container airtight, moisture-proof and convenient to use. The caps I have, not many! These lids will not snap onto the bucket without assistance. I think if you bought some SUPER WEATHERSTRIP CEMENT and sealed the lids with it it would work. This is my plan for her. I ordered two Gamma Seal Lids from Uline for less than what I paid for this POSER. live and learn
