This was my 2nd cover from them. My first cover was for a small wood holder for the outside. I have the diminutions from amazon and upload a pic of what I was covering. It fit perfect. The last cover I just bought: I needed a custom cover for my fire pit to keep it "dry" during the winter. I am an engineer and designed exactly what I wanted, and they took my drawing and made it happen. But all and all I am very happy. I definitely recommend them to anyone with custom or stock jobs. P.S. I only removed one star due to the communication difficulties we had with answering my questions.
