Rests on top of the black AIO wall of your AIO tank. Sturdy Lid Support: Acts as a platform for the back of your lid to rest on, making the lid multiple times more rigid and sturdy on top. No Jumpers in Filtration Section: With a full AIO Guardrail Kit, the gap between the top of the black AIO Wall and bottom of the Top Lid is filled completely, stopping jumpers from accessing the filtration section. We will be releasing standard AIO Guardrail Kits for each specific AIO tank soon. For now, an appropriate number of AIO Guardrails for adequate support is included with every Top Lid that needs it. If you'd like to order more AIO Guardrails to fully cover the gap to stop jumpers from getting into your Filtration Section, contact our team so they can choose the correct quantity and size of guardrails for you.
