Well, not entirely no. It will if you cut it to fit.
Better yet, if you have the base and no screen, get a GL1100 screen and cut it to fit. Then put a GL1500 vent in it.
Best. Screen. Ever.
I love mine. Of course Ive not tried the name brand expensive ones, but I can block the lower hole if its raining and close the vent.
If its hot, I can open the vent and have a ton of airflow!
On second thought, maybe its just the vent addition to any screen thats the best ever...
