Twist nut for 8020 extrusion - 6mmTube (12 pack)

This small piece of plastic twists securely into 8020-style aluminum extrusion and allows 5 to 6.5mm aquarium airline tubes to be managed.

This part, once twisted into place on the extrusion, can support four tubes and keep them well-organized while still leaving them visible.

Strong PETG+ construction is surprisingly sturdy for a small part.
