    5.0 out of 5 stars Totally works
    Reviewed in Canada on June 12, 2021

    I 100% regret my plan to build my own screen boxes. It was a long day of work, and many of them came out kind of funny looking. All that's my fault though, I expected to be a pro after watching 2-3 you tube videos and turns out it's not quite that simple.

    Still through, these corner pieces were very serviceable. Easy to use and definitely made the job more straight forward.

    5.0 out of 5 stars Fit the screen frame parts but slightly larger
    Reviewed in the United States on July 1, 2025
    Verified Purchase
    These fit the frame parts, but are slightly larger than the original corners they replace. You may need to shave off about 1/8 off the length of the aluminum frame parts if you replace all four corners and your screen fit is very tight. (Measure your screen before and after). However, quality is at least as good as the original parts and I had no difficulty repairing my screens using these parts for replacements.

    5.0 out of 5 stars When screen blew off, two corners broke
    Reviewed in the United States on January 13, 2024

    Product easy to use but the corners are fragile. My first screen blew off and two corners broke in two. Granted, two corners didn't brake so my review is necessarily 50/50.

    4.0 out of 5 stars These fit SUPER tight!!!!!! VERY hard to get in
    Reviewed in the United States on June 11, 2022
    Verified Purchase
    We had to hammer them in all the way. I couldn't put them in @ all by myself. Super tight in our screen frames. Made it easy to build our screens... Once we got them to go in all the way. Bent up the edges of our frames, but still worked. Doesn't look professionally done @ all, but the screens keep bugs out, soo meh
