That looks like the flip top portion of our 70-136 assembly. Could this be what you're looking for? Can you also specify what you mean when you ask how these work? These just help keep the screen frame in place. Is there anything in particular you wanted to know? |

Oh sure, I see what you mean now. Sorry about that. To remove the screen, you have to flip the plastic lever up. That will retract the pin from wherever its retained in the window frame and free the screen for removal. You may also find the video below to be helpful. |
