Garage door seal at the bottom: magnetic, flexible, rodent-proof – a perfect fit.
Is your gate letting in air or water? With the right gap seal, it will be airtight, quiet and reliable – without any DIY work.
Why this topic is underestimated
The best technology is of little use if the floor has gaps. Energy escapes, moisture gets in, and pests thrive. Good news: With suitable floor profiles and gap seals , you can create a clean seal – even on uneven floors. Here you'll find a quick selection, installation guides, and direct links to the right solutions.

Advantages & Benefits
The seal reduces energy loss and protects against dust and insects.
Less dirt on the closing edge – the gate runs more smoothly and safely.
Magnetic systems can be clamped on – often without any drilling.
Technical background
There are base profiles, magnetic additional seals, and optosensor profiles for the closing edge. This ensures a tight seal and compliance with standards.
Magnetic seals fit snugly against the bottom edge of the gate. Adapter strips are used for non-magnetic surfaces.
Wider seals compensate for slopes. This saves rework and significantly improves the seal.
Selection in 60 seconds
- Check the type of door : sectional door, roller door or steel door?
- Measure gate leaf - total length
- Measure the gap : low, medium, or large? Take a photo.
- Check the ground conditions : level, uneven, sloping?
- Choose comfort : magnetic, rodent-proof, with optosensor profile.

Application & Assembly
- Clean the floor, measure the gap, take photos.
- Plan for adapters if the surface is non-magnetic.
- Cut to length - shorten the width of the gate leaf, deburr the edges cleanly.
- Position the magnetic seal and apply it firmly.
- Close the gate, check the sealing line, and readjust.
- Optional: Integrate optosensor profile.
Check the sensors: The light barrier and closing edge must react cleanly. Then perform a short OPEN/CLOSE function cycle with visual inspection.

Practice, Acknowledgements & News
Logistics hall resealed to SAMTR 29. Result: less draft, smoother operation, less cleaning required at the closing edge.
Thank you for your measurement photos. This allows us to recommend the correct seal in minutes – without any mistakes.
Newly sorted: Floor profiles & seals – better filters, clearer descriptions.
Maintenance & Care
- Clean regularly, avoid harsh cleaners.
- Test the print: The paper strip must clamp.
- In case of wear: Replace the seal segment by segment.
Why we are the right ones
We combine sealing with sensors. That means: tight and secure. Just send us the gap measurement, a photo of the floor, and your gate type – we'll deliver the perfect combination.
FAQ
How do I seal the bottom of a garage door?
With bottom profile or magnetic gap seal. Measure the gap, select the profile width (door leaf width), install cleanly and test the function.
Which type of waterproofing is needed for uneven ground?
Wider, flexible profiles or magnetic additional seals like SAMTR. They compensate for slopes better.
Does magnetic sealing really hold?
Yes, it works very well on magnetic surfaces. Adapter strips are available for non-magnetic areas.
Can I combine sealing and an optosensor?
Sure. Optosensor profiles secure the closing edge, while the seal protects against drafts and water.
How do I measure the gap correctly?
Measure several points: left, center, right. Use the highest value as a reference. Take photos – done.
Which products are compatible with sectional doors?
Classic floor profiles or magnetic systems. For sensors: optosensor profile and suitable light barrier.
And what about roller doors/high-speed doors?
Magnetic additional seal like SAMTR 29/36. It sits above the lower lip and compensates for unevenness.
How do I maintain the seal?
Remove dirt, clean gently, no solvents. Check contact pressure; replace damaged segments.
Sealing is mandatory – we make it easy
Measure the gap, send a photo, and you're done. We recommend the right set consisting of seal, adapter, and sensor – and you only need to order once.
