(DISCONTINUED) – This is a replacement filter cover lockdown screw that will fit any of the Bestway, Coleman or Lay-Z-Spa brand of inflatable hot tubs. If you have lost or damaged your filter cover lock screw, this is a perfect replacement. No need to buy the entire housing to get a replacement. This one will do the trick. Though a slightly different design than the original, this part will work just as good as the original.
