The screen opens very easily from either inside or out by simply popping the screen out at the bottom with your toe. Then the screen rolls up smoothly and safely.
There is also an easy way engage the screen without bending over:
1) standing up straight, let out screen with your hands until it hangs down just below the hold-down hooks,
2) with your toe push the bottom bar to where the pegs at the end engage with the hold down hooks,
3) let the screen take up the tension until the screen is tight.
