Extend the lifespan of your equipment and watch garden birds with complete peace of mind thanks to this set of Ø4 cm replacement suction cups.

Over time, sunlight and temperature fluctuations can cause the original suction cups on your window accessories to lose their elasticity and grip.

This set of replacement suction cups has been specially selected to provide a strong, durable, and secure attachment to all your glass surfaces.

Why choose these replacement suction cups?

High-performance grip: Thanks to their optimized 4 cm diameter and quality flexible material, they create a powerful suction effect capable of supporting the weight of seed-filled feeders, as well as visits from the hungriest birds (tits, robins, nuthatches, etc.).

Weather resistance: Designed to withstand outdoor conditions (rain, frost, UV rays, wind), they maintain their flexibility and grip all year round.

Universal compatibility: Ideal for replacing worn suction cups on your window feeders, transparent nesting boxes, bottle waterers, or suet ball feeders.

Transparency and discretion: Completely transparent, they blend in with your windows and patio doors so they do not obstruct the view, allowing you to fully enjoy the spectacle of nature from inside your home.

Technical specifications: Diameter: 40 mm (4 cm)

Material: High-strength, transparent flexible PVC.

Compatibility: Attachment to glass, windows, and any perfectly smooth, non-porous surface.

Installation tips for optimal grip:

Surface preparation: Carefully clean the window in the desired location with window cleaner or white vinegar to remove any traces of dust or grease, then dry thoroughly.

Installation: Lightly moisten the inside of the suction cup, then press firmly in the center to push the air out.

Maintenance: To restore flexibility to suction cups hardened by the cold, soak them in warm water for a few minutes before installing.

Material:
All my creations are designed and manufactured by me using PETG, a durable material – more modern than wood!

• Durable: resists sun, rain, and frost without damage.
• Hygienic: easy to clean, no mold or parasites.
• Design: lightweight, strong, and aesthetic, with a modern style.

I chose to make my creations from PETG because, unlike PLA (which some sellers use), PETG perfectly withstands climatic conditions such as humidity, heat, UV rays, and frost...

Ultra-resistant outdoors: Fears neither frost, rain, nor summer sun (unlike PLA, which deforms in heat).

Healthy & hygienic for wildlife: Smooth and non-porous surface, ultra-easy to wipe clean to prevent disease transmission.

Professional durability: A technical and unbreakable material designed to stay outdoors all year round, season after season.

Zero maintenance: No need for varnish, stain, or chemical treatments toxic to birds.

The electricity for manufacturing is supplied by solar panels during the day and by decarbonized energy for the rest of the time!

These suction cups allow you to securely attach your feeders, drinkers, or birdhouses directly to your windows, glass doors, or French windows.

They are used to:

Replace worn suction cups that have lost their grip over time due to sun or frost.

Secure your equipment against the weight of the seeds and the movement of the birds.

Attach other lightweight accessories to any perfectly smooth and non-porous surface (tiles, mirrors, glass).

Fixing is achieved by simple vacuum pressure on a clean, smooth surface.

Clean the glass: Degrease the area with a little white vinegar or glass cleaner, then dry thoroughly.

Moisten slightly: Run a very slightly damp finger over the inner edge of the suction cup (this improves the seal).

Press firmly: Apply the suction cup against the glass by pressing firmly in the center to expel all air towards the edges.

Tip: If a suction cup is deformed or hardened by the cold, soak it in hot water for a few minutes to restore its flexibility before attaching it.

Yes. They are made from a flexible material resistant to temperature fluctuations, rain, and UV rays. To ensure they hold perfectly in the middle of winter, simply ensure you install them on a clean window at room temperature (or moistened with lukewarm water).

Pass the head of the suction cup through the slot provided on your feeder. Its flexible material deforms to insert easily and returns to its original shape to ensure a perfect lock.

They cling to all perfectly smooth, rigid, and non-porous surfaces: window panes, bay windows, verandas, mirrors, or outdoor tiles. They are not suitable for rough, wooden, or frosted surfaces.
