Which type of lockset is most commonly found in residential properties?

1. Mortise lockset

2. Cylindrical lockset

3. Center hung pivot lockset

4. Pre-assembled lockset

The correct answer is: Cylindrical lockset

The cylindrical lockset is the most commonly found type of lockset in residential properties due to its design, ease of installation, and cost-effectiveness. These locksets consist of two cylindrical sections, one on each side of the door, which can easily accommodate a variety of door types and thicknesses, making them highly versatile for residential use. Cylindrical locksets typically provide adequate security for residential applications, while being straightforward to operate for everyday use. Their straightforward mechanism allows for both keyed and non-keyed options, granting homeowners flexibility and control over access. In contrast, options like the mortise lockset are generally used in more specific applications, providing a higher level of security but requiring more complicated installation processes, making them less common in standard residential settings. Center hung pivot locksets are less frequently used in residential architecture and are more often seen in commercial applications with specific design features, whereas pre-assembled locksets might refer to a variety of products without the same clear reference to residential norms. This makes the cylindrical lockset the preferred choice among homeowners for its balance of accessibility, ease of use, and security.
