Description
Coast Spas weir floating door subassembly in the GMB finish that controls how water enters the skimmer. The door helps the skimmer grab surface debris and keeps air from being drawn into the circulation pump. A worn or missing door often leads to weak skimming and pump air locks. It comes as a complete subassembly. Verify the finish and skimmer type before ordering.
