A deadbolt lockset is a type of locking mechanism commonly used on doors to enhance security. Unlike standard spring bolt locks, deadbolts require a key or a thumb turn to operate, making them more resistant to forced entry. They are typically installed on exterior doors and come in various styles, including single-cylinder and double-cylinder options. Deadbolt locksets are designed to provide an extra layer of protection for homes and businesses. The solid metal bolt extends into the door frame, making it difficult for intruders to manipulate. Many deadbolts also meet specific security standards, ensuring they offer reliable protection against unauthorized access.
