I have a window pane close to a door handle. If the window glass pane is broken by a burglar. They can reach the door handle on the inside through the broken window pane and grill behind. This is a security risk. I am looking at solutions, the feasible one that appears to me is to have an additional closely spaced grill onto the larger grill. So that the door handle may not be reached from the window. Does anyone know of a mesh grill that I may use and/or any alternative solution to this?
