GN 437.4 Hinges 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.

The -3° of the type C2 moreover ensures that the door or cover presses slightly against the housing frame when closed.
