It was saved because exactly the size I wanted is saved, but since a crochet sound comes out when the tension goes out, I want you to sell vinyl tubes that fit exactly in the sense of prevention of cissing, dirt, rust prevention.
I bought 2 pieces at 1/28 cash on delivery. Free length 197.2 mm. Length under load 272.03 mm. Permissible load 140.24 N. We intend to use it under conditions. I used the two in the same way, but one of them has increased free length. I think that it is overloading about 7 mm, please tell me the environment where the free length will grow.
