I was looking for a method of fixing the 6 Φ cable through the small case of Takachi. I chose grommet because I did not fit in the case when I made it to Bush. Takachi also deals with grommets, but it seems that we do not have available for 6 Φ cable, so choosing this was the correct answer. It is hard to embed it in the mounting hole because it is hard rubber, but it is satisfied because it will not come off unless it is deliberate pushing force when passing through the cable.
It is a product without any worries or problems. However, pay attention to the number of lots. I made a mistake and a ridiculous number arrived (laugh)
