Grommet

Not much. Guess I was lucky when I order the gromet as it said last one in purple. Had an issue with one that came with the enclosur, and I had to cut it out as the threads didnt line up when put in. I might order a replacement side planed as I put a couple of scratches in it. Very happy with the company products so far as well as the price compared to other enclosures I had seen.
