Understanding Sliding Patio Door Locks
Types of Sliding Patio Door Locks
Mortise Locks
Mortise locks are installed inside the door frame, making them sleek and unobtrusive. They are known for their durability and secure fit. If your sliding door has a mortise lock, it likely sits flush with the edge of the door, providing a clean look while offering solid security.
Hook-Style Locks
Hook-style locks use a hook mechanism that latches onto a strike plate on the door frame. These locks are great for added security as the hook makes it difficult to pry the door open. You’ll find these often in patio doors that need a bit more protection against forced entry.
Loop-Style Locks
Loop-style locks feature a loop that catches onto the door frame. They are straightforward and easy to operate, making them a popular choice for many homeowners. While they might not be the most secure option, they offer decent protection for lower-risk areas.
Keyed Locks
Keyed locks provide the highest level of security among sliding patio door locks. They require a key to lock and unlock, adding an extra layer of protection. If security is your top priority, a keyed lock is an excellent choice. Plus, having a keyed lock means you can easily integrate it with your home’s overall security system.
