What type of lock set is commonly found on closet doors?

The choice of a passage lock set for closet doors is primarily due to its design and functionality. Passage lock sets are utilized for interior doors that do not require any locking mechanism to secure the space, which is perfect for closets where privacy is not a concern. They allow free movement between rooms without the need for a key or locking feature, making them convenient for areas like closets where quick access is desired.

In contrast, privacy lock sets are intended for spaces that require a degree of privacy, such as bathrooms or bedrooms, since they can be locked from the inside. Deadbolt lock sets provide a higher level of security, typically used on exterior doors to prevent unauthorized entry, while entrance lock sets are designed for exterior doors and come with both a locking mechanism and a handle, serving a different purpose than what is needed for a closet.

Thus, the passage lock set stands out as the ideal choice for closet doors, aligning with their function of enabling easy access without the need for a locking feature.
