8" suction cup frag rack
This a frag rack that holds 23 frags and it mounts with suction cups. These are not your normal suction cups, there is a dial on the back of them, the more you turn it the more tension you put on the suction. Very durable. (3) 16oz bottle of coke were put on these racks and they did not fail and were test after a year of being in saltwater.
Suction cups are more for acrylic tank owners of fear magnets will scratch or someone looking for a lower price point.
