When the chain is too long, it can cause the door gap to be too large, increasing insecurity. After repeated experiments, we finally determined that the length of the chain is between 165mm-170mm, with a 30mm end and a total length of 195mm-200mm, which is enough for you to observe the situation outside the door. This is a suitable length.
