Pull-out Window Security Safety Grill Grille Home Protection Shed Bars Steel V2Aox, Size:60 x 50 - 65 cm

This is an excellent product. The point to consider when buying is that it has only two fixing points each side. These are too close to the edge, so could be difficult to drill corresponding holes if this is to be fixed near the window sill etc. I needed to drill alternatives. I also added a fixing point in the middle although sure if that was essential. In any case, drilling this material is not too difficult so long you have the correct drill-bits. It is supplied with 4 screws and plugs. You need to consider if these fit your particular need.
