What is a characteristic of cylindrical locksets?

They cannot be installed in pre-drilled holes
They are extremely expensive and rarely used
They are simple to install and commonly used
They only come with keyless entry options

The correct answer is: They are simple to install and commonly used

Cylindrical locksets are widely recognized for their design and ease of installation, making them a popular choice in both residential and commercial applications. Their construction typically allows for straightforward mounting in standard pre-drilled door configurations, which streamlines the installation process. This simplicity is a significant advantage for contractors and homeowners alike, as it reduces labor time and costs associated with installation. Additionally, their commonality in the market means that they are readily available and come in a variety of styles and finishes. Other characteristics, such as being overly expensive or limited to keyless entry options, do not accurately represent cylindrical locksets which are often economical and versatile. Their versatility also allows for the inclusion of a range of locking mechanisms, including key-operated versions. Thus, their combination of ease of installation and widespread use emphasizes why they are considered a staple in the realm of door hardware.
