• Adjustable Security Bar: This sliding door lock easily extends from 15.7 to 26.75 inches and can be installed on patio doors, sliding glass doors, and it can also act as a balcony door lock; it can be adjusted to allow the door to partially open for ventilation while being secured and locked

• Indoor Security: The patio door security bar and saddle are screwed into the door frame and profile, providing reliable protection, unlike the pressure-mounted bars that can shake loose and fall; with its simple installation and sturdy build, the sliding door security bar will remain securely mounted in place
