## Long description

sera double suction cups for heaters model 21281 are mounting accessories designed to fasten cylindrical aquarium heaters and similar devices to glass surfaces. The set contains two suction cups connected by a short holder that supports a heater’s body and keeps it aligned parallel to the aquarium wall. These suction cups enable adjustable placement of a compatible sera heater to ensure stable and accurate water temperature control without drilling or permanent fixtures.
Advantages
The double suction cups provide a secure and low-profile mounting solution that resists typical aquarium vibrations and water movement. Their design allows easy repositioning along the glass surface and straightforward removal for maintenance. Made for use with cylindrical heaters and similar equipment, the accessory keeps the heater stable and minimizes contact with substrate or decorations.
Suitable for
Mounting cylindrical aquarium heaters to glass walls
Temporary or adjustable placement of heaters during maintenance
Affixing other cylindrical aquarium equipment that fits the holder
Key specifications
Mount type: double suction cup holder for glass surfaces
Compatibility: designed for cylindrical aquarium heaters and similar devices
Attachment method: suction-based, non-permanent
Material characteristics: water-resistant mounting components suitable for aquarium environments
Quantity: pair of suction cups with connecting holder
How to use
Ensure the glass surface is clean and free of algae, film or debris; wipe the area with a soft cloth before installation. Press the suction cups firmly against the inside of the aquarium wall until they adhere, then position the heater within the holder so it sits securely and parallel to the glass. To adjust position, gently release one suction cup if necessary and reapply at the new location. Remove the assembly by detaching the suction cups and clean both cups after extended use to maintain adhesion.
Usage recommendations
Check compatibility with the heater diameter before installation and avoid mounting on curved or textured surfaces that may reduce suction effectiveness. Periodically inspect suction strength and reattach as needed to prevent the heater from shifting. For long-term installations, clean suction cups regularly to maintain a safe and stable attachment.
