Although I built several screen lids for tanks I never trusted the rubber splines to securely hold the screen. What I did was complete each lid, securing the screen with the rubber spline, then I filled all the spline grooves with marine silicone sealer, available at Home Depot or Lowe's. That sealer holds everything in place and I never had a spline come out, despite the snakes pushing hard on the screen at times.
