Ground-floor windows are the entry a locked door redirects people to · review
A hinge-side security bolt for inward-opening windows — the side almost nobody reinforces. ABUS states the bolt protects up to one metric ton of pressure and rates it at security level 10 on its own scale.
The conclusion The one people leave out, and the one that decides whether the others matter. Fit it alongside a handle-side lock, not instead.
Almost every window lock sold is for the handle side. A window levered on the hinge side leaves the frame with its hinges attached, and every handle-side lock in the house is still engaged when it happens.
Because it looks solid. The hinges are metal, they are screwed to the frame, and they clearly hold the window shut. What they hold it against is being pulled open, not being prised sideways out of the recess — and once the leaf has moved a few millimeters, the hinge pins are irrelevant.
A bolt designed to resist up to one metric ton of pressure, and security level 10 on the company’s own scale, which it applies across its range and which goes above 10. Both figures are ABUS’s, reported here as such: this site is not a testing body.
The frame is the honest limit. A bolt rated to a metric ton, screwed into a lining that splits at a fraction of that, is a bolt rated to whatever the lining holds.
This is a complement to a handle-side lock, not a substitute. Securing one side and not the other moves the problem rather than solving it, and the two together are what makes the window awkward on both edges.
Anybody who has already fitted handle-side locks and thinks the job is done.

Because a window levered on the hinge side comes out of its frame complete with the hinges, and every lock on the handle side is still engaged when it does. Reinforcing one side and not the other simply moves the attack. This is the product for the side people forget.
It is the manufacturer's statement of the pressure the bolt is designed to resist. It is a figure ABUS publishes and not one measured here, and it describes the bolt rather than the frame it is screwed to — which is usually what gives way first.
Yes. It is not an alternative. A window wants securing on both sides, and the two ABUS products in this hub are designed as a pair rather than as competitors.
