Have you found the perfect device to attach to your tanks rim, only to find the device isn’t wide enough to fit your tanks rim?
This adapter allows you to convert a tank rim up to 1″ down to a 12mm rim.
Bolt screws are 15mm(.5in) below the top of the rim to allow for a rimmed tank design.
Perfect for small fans, lights, etc.
Works great for the Londafish Aquarium Fish Fan off of Amazon. (Will need 2 rim adapters for this fan)
Sold as a single rim adapter.
