Ground-floor windows are the entry a locked door redirects people to · review
A lockable window security bolt in a zinc die-cast housing, which BURG-WÄCHTER states can be fitted on the top, bottom or handle side of a window or balcony door with a few holes.
The conclusion The one to buy when the handle side is not the right place. Fit two on anything tall.
Most window locks assume the handle side is where the lock goes. On many windows it is not.
A tall casement flexes in the middle. A balcony door is levered near the bottom, where the leaf is heaviest and the frame least supported. A wide window twists. The point of failure depends on the window, and a lock that can only be fitted in one place is a lock that sometimes goes in the wrong one.
BURG-WÄCHTER states this unit fits top, bottom or handle side. That is the reason to choose it.
One lock is one point. On anything tall or wide, two — top and bottom — stop the leaf being flexed far enough to release. Push a corner of the window with your hand: wherever it moves is where the second one belongs.
Zinc die-cast rather than folded sheet metal. It resists twisting and peeling, which is what a small window lock is asked to do. It is not hardened steel and this page does not pretend otherwise.
This one needs the key to lock as well as to open, which is less convenient than push-to-lock designs. Hang the key within reach of the window and out of sight of the glass — a locked window with the key downstairs is a problem in a fire.
Balcony doors, tall casements, and any window where the handle side is not the weak point.

Because a window is levered where it is weakest, and that is not always the handle. A tall casement flexes in the middle; a balcony door is often attacked at the bottom. Being able to fix at the top, the bottom or the handle side means the lock goes where the window needs it rather than where the packaging assumed.
One is a locking point. On a tall or wide casement, two — at top and bottom — stop the leaf being flexed enough to disengage. Look at the window and imagine pulling its corner: where it moves most is where the second lock belongs.
It is a solid casting rather than folded sheet, which resists being twisted or peeled. It is not hardened steel, and no listing here claims it is. For a retrofit window lock it is the appropriate material.
