Which type of lockset allows for the simultaneous retraction of multiple bolts?

1. Single Cylinder Lockset

2. Interconnected Lockset

3. Deadbolt Lockset

4. Mortise Lockset

The correct answer is: Interconnected Lockset

The interconnected lockset is designed to allow for the simultaneous retraction of multiple bolts. This feature is particularly useful in scenarios where ease of access is required, such as in residential or commercial settings. With interconnected locksets, when the door handle is turned, both the latch and the deadbolt can be retracted at the same time, facilitating a more efficient way to open the door without the need to fumble with multiple mechanisms. In contrast, single cylinder locksets typically involve only a single locking mechanism, relying on either a key or a thumb turn for operation, which does not provide the ability to retract multiple bolts simultaneously. Deadbolt locksets usually focus on providing an additional layer of security and operate independently from the door handle. Mortise locksets may provide a more complex locking solution but do not inherently enable the simultaneous retraction feature of interconnected locksets, as they can still operate in isolation for their deadbolts and latches. Thus, the interconnected design stands out for its functionality in this context.
