Why a kit

One latch shouldn't be the only thing holding your patio door.

The latch on a slider is small, and the door usually faces the back of the home, out of view of the street.

The bar and the lock mean the latch is no longer working alone. The alarm adds noise right at the glass.

Hold the door. Then make it loud.

Where each piece goes

Door first, then the window beside it.

The bar goes in the bottom track. One lock goes on the door frame. One alarm goes on the door glass.

The second lock and alarm go on the next sliding window, or on a second slider if you have one.

Who it suits
