The spring hinges allow the door to open at 180 degrees,
useful in restaurants, shops and premises where you can easily access even using your own body to open them on both sides.
In this video I do the step by step assembly of the hinges in a small door showing all the assembly phases,
from the preparation in the laboratory to rule out any defects and difficulties, up to the implementation in the place of destination.
As always, I hope I've been useful ...
Thank you.
