Aqua Lily Pads are an evolutionary product, constantly finding ways to produce better, safer, more durable products. Because of this philosophy, Aqua Lily Pad has recently designed and invested in the development of a proprietary Tether Snap (grommet) mold. The design incorporates a “one-time snap” design that is easily installed when purchased as an accessory. The primary tether system comes factory installed on our pads and has no sharp edges or points. Because it is not metal, it does not get excessively hot in direct sunlight nor does it pose a hazard to exposed body parts from extreme heat. Additionally, Aqua Lily Pad also replaced the previous galvanized metal spring clip with a superior marine grade nylon spring clip which will never corrode in fresh or salt water environments.
