What is the primary function of a latchset?

1. To secure a door with a key

2. To hold a door in position without locking

3. To offer a wide variety of locking options

4. To allow a door to swing freely

The correct answer is: To hold a door in position without locking

The primary function of a latchset is to hold a door in position without locking. A latchset is designed to provide a mechanism that allows a door to close and remain closed while still permitting easy opening without the need for a key. This function is essential for interior doors where privacy is a concern but security is less critical compared to external doors. The latch operates through a spring mechanism, ensuring that the door securely holds its position when closed, yet can be easily opened from the opposite side, allowing for safe entry and exit while providing a degree of accessibility. In contrast, other options describe functions that may relate to locking or security mechanisms but do not represent the core purpose of a latchset. A latchset does not typically involve a key for security, as seen in the option mentioning securing a door with a key. Similarly, while latchsets may come in various styles, their primary role is not to offer multiple locking options, as indicated by one of the other choices. Lastly, while a door may swing freely when a latch is disengaged or when a latchset isn't present, the fundamental design of a latchset focuses on holding the door in a closed position rather than allowing it to swing without any resistance.
