https://www.youtube.com/watch?v=jIHkOBZlZwg&feature=youtu.be My girlfriend had been constantly telling me to shut the mosquito screen, but my ADHD prevented me from hearing her, so I let out a sigh and took care of it once and for all - no more buzzers! Instructions: Use a 13mm bearing or not; I used neither in the video. A bearing will reduce the weight you need and make opening the door easier. Attach an electrical wire to the top rail of the mosquito screen's track, securing it firmly. Fasten the pulley using a 6-32 nut and bolt on the main rack. Install the string on the wheel by hooking it onto the wire at the top. Add counterweight on the opposite end of the wheel. I chose metal rods; you can do the same or find another sturdy material that fits your needs. I hid these rods within a pvc pipe to ensure smooth movement while still giving some direction to them. Keep in mind, there may not be space at the top of some doors due to this setup; no problem! It's an easy modification - just attach everything to the front part of the mosquito door.
