Folding Hub & Lateral
With this unique, all-in-one hub and lateral system, the riser pipe is attached before insertion. Then the pivoting laterals are locked into position using an S-hook device. The patent-pending lateral design creates a more vigorous backwash and high flow rates from just six laterals. Designed to fit a 4-in. opening, models are currently available for 16-, 18-, 21- and 24-in. tanks.
