acrylic overflow template

[reefman]

I've made a template in cardboard that will cover my overflow so snails cannot crawl over. Any1 know where i can find a place in queens that will sell and cut a piece of acrylic for me. it's a custom triangular shape but 2 angles are rounded off and a hole(about 3" dia) near the middle.

What going to stop the snails from going into the 3" hole? Is it a HOT overflow?
Im off this week, staying home with my son. Friday i have to go pick up some ribs for a very patient member of MRs canopy at work.

Define: "2 angles are rounded off" do you mean two sides?, also "triangular shape" is it acute, obtuse or other?
I might be able to make this for you.
