If you can get your fingernail under the grommet, then it is not seated properly. Whether the grommet washer faces the bag or faces away from the bag does not appear to matter. When the grommet is properly seated boths sides of the grommet are snug with the material. On loose grommets, a line can snag on both sides of the grommet. In addition to a suspension line snagging a grommet on the tongue type closing loop, a line may half-hitch around the tongue.
Grommets loosen with age.
Ensure proper placement of suspension lines in container. Deploy face to Earth. Remove a tongue type closing loop. Their help and unselfish giving of their time to answer a long list of questions is very much appreciated by myself and anyone that learns to reduce the probability of occurance of these very dangerous malfunction modes. Many other manufacturers were also contacted, but have not yet replied.
