Thickened wire rope with metal base ABS protective cover, window limiter requires punching installation. Includes 4 screws, 1 key, window safety lock for both inside and outside installation, suitable for push and pull application.

Haven't tried it yet but it seems very good and easy to install! Be careful, it's just for closing when you're there, it can't be used as a security feature!

perfect, the only thing i thought was self-adhesive, it's screwed even better, of course, someone just has to put it on

pleasantly surprised by the quality of these, stronger than expected, works well so far, we attached the little key that comes with it onto the wire at installation so it won't get lost
