Ground-floor windows are the entry a locked door redirects people to · review
A telescopic bar clamped into the window reveal rather than screwed to the frame — vertically, horizontally or diagonally. SCHMIDT states 101 to 175 cm (39.8 to 68.9 in) of adjustment, rubberized pressure pads, and a deliberately visible orange finish.
The conclusion The tenant's answer, and the most visible deterrent here. Test the reveal before relying on it.
The bolts in this hub screw to a window frame; this one is not screwed to anything. For an inward-opening window, that makes it the option for the substantial number of people who are not allowed to drill — on a sliding window, the hub’s clamp locks are the other no-drill choice.
A telescopic bar, extended until it clamps between the two sides of the window reveal — vertically, horizontally, or diagonally, with swiveling contact faces so it seats on an uneven surface. Rubberized pads spread the load and leave no mark. SCHMIDT intends it for inward-opening windows, French doors, patio doors and basement windows: it clamps behind the sash.
Force applied to the window then goes into the masonry, which is where you want it. The window frame is no longer what takes the load.
The reveal being solid. A rendered masonry return is ideal. A plasterboard return, a dry-lined reveal, or crumbling stucco is not, and the bar will pull through it. Press hard with a thumb before deciding.
Orange, visibly so, and SCHMIDT states it is meant to be seen from outside. That is the correct thinking: a window that obviously cannot be opened is a window nobody chooses. Fitted close to the glass, it does most of its work before anybody touches anything.
The window cannot be opened while it is in place, and it is conspicuous indoors. For a room used every day, that becomes tiresome. For a ground-floor window in an apartment you are away from, it is exactly right.
Tenants, vacation rentals, and anybody whose landlord says no holes.

It transfers force into the masonry reveal rather than into a window frame, which is structurally the right direction. What it depends on is the reveal being solid — a plasterboard return or crumbling stucco gives way, and the bar comes with it. Press the reveal before trusting it.
Deliberately. SCHMIDT states the bar is meant to be seen from outside, and the closer it is fitted to the glass the more visible it is. A window that visibly cannot be opened is a window nobody starts on, which is the cheapest form of security there is.
That is the main reason it exists. Nothing is drilled, nothing is altered, and it comes away when you leave. For a rented apartment, a student room or a vacation rental, it is the no-drill answer for an inward-opening window; the clamp locks in this hub do the same job on sliding windows.
