Highlights

🔌 NO OUTDOOR OUTLET? Run power — or a hose — straight through your window or lanai screen. No cut-up mesh, no door propped open, no bugs getting in.

Most homes don't have an outlet where you need one. So the extension cord goes through a cracked-open slider — letting in mosquitos, letting out the AC, and leaving a door you can't lock. Or worse, someone takes scissors to the screen. This magnetic pass-thru ends all of that: three tiny slits (no mesh removed), 10 neodymium magnets sealing both sides, and a hinged flap that closes flush around your cable or hose.

💡 PAIR DEAL — choose the 2-Pack option and save $7 ($25 instead of $32). Most homes want one at the front door screen and one on the lanai.

🏠 WHAT PEOPLE USE IT FOR
• Extension cords to the lanai — string lights, fans, party stereo
• Generator cord INTO the house during a power outage — no door wedged open in the wind and rain
• Portable AC or dehumidifier drain hose
• AC condensate drain line
• Aquarium water changes (drain the tank to outside)
• Powering outdoor holiday wreaths and window-hung lights from inside
• Garden hose from an outside spigot to inside
• Phone/laptop chargers out to the porch
• Ethernet, Starlink, or solar panel cables
• RV window power

📦 WHAT YOU GET
• 1 Screen Pass-Thru (inside plate + outside plate + hinged flap)
• 10 high-grade neodymium magnets (pre-installed)
• Fits any standard window, sliding door, lanai, or pool cage screen mesh
• PETG plastic — UV resistant, weatherproof, won't crack or warp outdoors
• Your choice of color (White, Gray, Beige, Brown, or Black)

🛠️ HOW IT INSTALLS (60 seconds, one razor blade)
1. Pick the corner of your window or lanai screen where you want the pass-thru
2. Hold the inside plate against the screen as a template, mark the 3 triangle peaks
3. Use a razor to cut 3 slits from each marked peak to the center — no material removed, just slits
4. The 3 mesh flaps fold back and tuck inside the product cavity (hidden from view)
5. Snap inside and outside plates together magnetically through the mesh
6. Open the bottom flap, feed your cable or hose through, close the flap

📍 RECOMMENDED PLACEMENT
• BEST location: LOWER LEFT or LOWER RIGHT corner of your screen — gravity pulls the cable straight down with no strain on the screen mesh
• Upper corners CAN be used (handy for Christmas wreath cables or window-hung holiday lights), BUT the cable or hose must hang with NO strain on the screen — support the weight separately
⚠️ Any strain on the screen mesh from a hanging cable will stretch or tear it. The product itself stays put — it's the cable weight that does damage. When in doubt, mount low

💪 BUILT TO LAST
• PETG plastic — same material we use for our pool drain inserts and shop vac adapters
• Outdoor-rated and UV resistant
• Magnets hold tight in wind and weather
• Removes cleanly when you don't need it anymore — no adhesive residue. The small slits stay hidden in the corner and can be sealed shut with screen repair tape if you ever want to fully restore the mesh
