This round threaded grille is manufactured by Balboa / HydroAir and is part of the "Strip Skimmer" assembly.
This type of skimmer is often installed on round and/or compact spas. We also recommend it for the design of wooden spas.
We also offer, from the "Strip Skimmer" assembly, the face plate, gasket, wall fitting, straight nut (1.5-inch or 50 mm), and 90° nut (1.5-inch or 50 mm).
Note: for a wooden spa, an extended wall fitting is available.
