Trying to improve the security of my basement windows; need to anchor steel flanges to each side of the window casing(?) and the concrete block behind it.
Needs to be removable for glass repairs, etc.

Anyone seen anything like this?

 

What kind of windows do you have? Wood, metal, vinyl?? Double hung, casement, awning?? If they are removable, how secure will that be, once the glass is broken and access is gained to your bolt heads? Just curious. You may want to post a pix or two of the windows, no close ups, so we can see what you see.

 

Might be a few days for the pix, as I have camera "issues" right now...

 

As requested, here's a pic.
Window frame is approx. 12" x 33".

My idea is to fasten a length of steel angle centered horizontally across the window. This will have a welded flange at each end that will be drilled for 2 fasteners into the concrete blocks. The steel angle may also have some sharpened "decorations" on it so the crackhead/methhead may leave some DNA evidence...

 

Is this a legal egress window? If not, what you propose may work. If the walls are solid, use Red Head mushroom type fasteners. Not even you can get them out if installed properly. Some drive in with no heads, and others use nuts to drive down and tighten. If the walls are hollow block, you may use wing type mollies after drilling the appropriate sized hole in the block and window.

We live in the country, so there's no problems as you describe, but some of the "kids" around, thought it cute to break off the street signs at intersections. I got tired of having to go to the county and having them replace the signs. So I just ground off the top edge of mine to a razor sharpness. It got bent, but is still in place Probably a shock to the perp. Now he has to tell mommy what happened. That's better.

 

Chandler......I AM shocked at you
