Bugs Stay Out

No More Light Gap
My bedroom door had a gap that let in hallway light. Couldn't sleep with it on. This fixed it — door closes and it's dark. Does exactly what it says. — David K., California

SEAL · PROTECT · COMFORT
Helps Reduce Drafts Automatically
The moment your door closes, the rubber seal drops down and closes the gap. When you open the door, it lifts back up automatically — no dragging, no contact with the floor, no marks left behind.
Designed to help reduce drafts, dust, noise, insects, and unwanted light from passing under the door. One seal. Multiple problems addressed at once.
Installation takes four steps: measure and mark, drill pilot holes, screw in place, and test the door. No special tools required. No cutting or routing to the door itself.
The aluminum body is built to last. The rubber seal is flexible and wear-resistant. Once it is on, it works quietly in the background — every open, every close, every day.
SMART · SIMPLE · AUTOMATIC
One Install, Every Day
When your door opens, the seal lifts automatically out of the way. When it closes, the rubber seal drops down and closes the gap beneath it — helping reduce drafts, dust, noise, and light from passing through without any effort from you.
Surface-mount directly onto your door — no cutting, no routing, no handyman needed. Adjust the plunger once during installation and the mechanism does the rest, every single time.
The aluminum housing is durable and low-profile, sitting flush against the door face. It is designed to blend with any interior style without drawing attention — functional without being visible.
No batteries, no electricity, no app — just a simple mechanical system that works quietly in the background, day after day. Nothing to charge, nothing to replace, nothing to remember.
Works on most standard interior doors with a flat bottom surface — bedroom doors, home office doors, laundry rooms, or any space where you want more comfort, quiet, and privacy.
One small upgrade. Year-round comfort.
Watch Before You Install
Two versions, two simple installs — pick the one that fits your door.
Frequently Asked Questions
What size doors does this fit?
The seal measures 36 inches (915mm) in length, making it suitable for most standard residential interior doors in the US. Always measure your door width before purchasing to confirm compatibility.
How does the automatic drop-down mechanism work?
An adjustable plunger on the hinge side of the door presses against the door frame as the door closes. This triggers the internal mechanism and lowers the rubber seal to the floor. When you open the door, the pressure releases and the seal automatically lifts back up.
Will it scratch or damage my floors?
No. Unlike traditional door sweeps that drag across the floor constantly, this seal stays raised while the door is open. It only contacts the floor when the door is fully closed — safe for hardwood, laminate, tile, and vinyl flooring.
Does it require batteries or electricity?
Not at all. The mechanism is entirely mechanical — no batteries, no wiring, no charging required. It works reliably every time using a simple plunger-activated system.
