This is a 8 inch Spring-Loaded Coin Release Weir. This Coin Release Weir is a universal weir for 8 inch skim filter boxes. All of our Coin Release Weirs are 5-1/4 inches wide.
Skimmer Weirs allow water to flow into the skimmer but close down when the pump shuts off. This prevents the back-flow of debris from returning to the pool. The String Release style works by simply positioning the weir into place and pulling out the string at each side. The rod springs and locks into place.
