Hinges GN 437.4 with detent hold door and covers in the given indexing position without additional mechanics.
This is particularly advantageous when machines and systems must be frequently opened and closed for loading and unloading, and it is also useful for servicing or repairs. Undesirable independent closing and opening is prevented.
Due to the front indexing position of approx. -3°, type C also ensures that the door or flap is pressed lightly against the frame when closed.
