Ideal for diversifying your spa experience for better and more relaxing hydrotherapy, the Waterway Poly Storm Twin Roto is a jet internal measuring 3-3/8" across its face with a length of approximately 4-1/2". It is designed with a five point scalloped escutcheon that enhances grip and highlights its expert build, making it a premium choice in spa retrofitting. Its roto-designed nozzle is great for providing a rotational stream of water in a single direction for improved water pressure that will help loosen tight muscles and massage sore joints. This jet internal is a perfect replacement for spas that use snap-in style jets. Available in Gray.
