WORKED PERFECTLY
I had 6 window screens for which these plastic pieces had rotted, so the screens were falling apart. Everything else about the screens was fine, so I did my research and found these new plastic pieces. I watched a YouTube video on how to replace these plastic pieces. I measured carefully and ordered the right size. I was able to do just what they did on the YouTube video, which was carefully pull out the spline near the corners, replace the corner plastic pieces, and then push the screen and spline back into the channel and VOILA! It went PERFECTLY! It took me about 20 minutes per screen. Saved me around $80 per screen to have them remade at ACE Hardware. So, that's a savings of around $480. Very happy I tried this project, saved the money, and developed confidence in this new handywoman repair job.

Not "3/4 X "5/16
If you are making completely new frames, these will work for you. As stated, they are not "3/4 inch corner blocks. They are '13/16ths. subtract "1 5/8ths from you overall measurements for each run. Also they say they are "5/16ths, again not true. You have to clip the edges off, not hard to do but why? Another issue, you need to clip a small post off the inside to allow the spline to go around the corners. Other than that, they work fine.

インチ表示なのでミリ変換が必要
欲しくてかなり探した商品でしたが、現物を比較した結果何とかなりそうです。ただ数量50個はやはり多いです。4の倍数で販売して頂けると有り難いです。
