The optimal solution for Koi ponds is one with a robust rim, ensuring minimal risk of injury when someone stands on top of the lid. The weight is evenly distributed along the ring that rests on the bottom of a standard bottom drain. This design facilitates maintenance by inserting and removing the lid with a koi net handle.
The lid is constructed from polyethylene (PE) and stainless steel, while the bottom ring is also made from polyethylene (PE). The dimensions of the lid are 35 cm x 1 cm, and the dimensions of the bottom ring are 21 cm x 2 cm. The total height of the lid is 20 cm. Please note that the lid and bottom ring are separate parts due to shipping size considerations. However, they are easily assembled.
