If we are honest, when considering a front door, who thinks of the word hasp unit? Correct, nobody. Nonetheless, we have been racking our brains in this regard as the hasp unit is one of the most important elements in closing a door, especially when it should be shut as securely as possible.

Incidentally, the results of our thinking are more than worthy of note. Here are a few buzzwords as a summary:
