DIY help asked for old custom aluminum frame plastic screen frame corners

Why not just buy the aluminum too. Then you know you get the right part. There is no guarantee that corners from one brand will fit another. Ace will make it up for you for a few bucks more than the parts so I stopped screwing with them.

I've never had those kind of screens - but a quick amazon ca search reveals quite a few - 7/16 x 3/4 seems a common size :

Ace was my first stop before I did it myself.

They looked at it and just shook their head. They fix windows but won't touch those aluminum ones.

Must be a local thing. They do here.

Thanks for the advice as I've never repaired these screen corners before. o I have tons of these screens; I just want to know how to _fix_ them.

It turns out mine are 7/16th in height, whereas the ones I bought were only

It's strange that the _only_ dimension that matters is the thickness; but that apparently is the case (according to a few calls today to suppliers). o 5/16ths

The key question now is do I buy the aluminum corners or the plastic ones. o

And can I replace them _without_ having to take the entire screen apart.

If you find a way to do that - post the video for us all !

You'd need to detach the screen on each side of the corner to provide slack to install the new corner insert. X 4. You might-as-well remove the screen completely ; install new corners ; install new screen with new spline. John T.

After you do all that you might as well just buy the aluminum and make new screen frames. Just don't go nuts tightening the screen or it will bow the frame in.

Yup. Unless you were fond of the old frames for some reason ? ... faded & matching the window frames ? .. stronger than the modern replacements ? ... dunno. John T.

I suppose you could just sand down the replacement corners to fit the frame metal.

Amen!!!

For me it's usually a storm window that's cracked. Yes they have to be disassembled, at least take the top section out, and that's where the corner pieces go.

Having done it a couple of times, I advise: don't even think about going back with glass. You WILL break it forcing in. Get a piece of Lexan.

The corner pieces hold it together and they're going to break anyway. So don't even try to save them. Use a Dremel cutoff disk and just slice them along the corner miter.
