Door straps (couple)
Couple of straps useful to install the Ercolina on every door. Must be installed so that the pull direction is same the direction of the door closed.
This couple of straps must be inserted in the Ercolina rear plate squared holes , one for each side, when the door is closed the Ercolina is very stable.
It is preferrable to close the door with the key so that nobody can open while using the Ercolina.
