  • Return fitting with releasable cap
    Patent number: 4951326
    Abstract: A retaining ring of an eyeball return fitting of the type used in swimming pools and spas is provided with a releaseable or breakaway cover cap. The cap closes the end of the return fitting during construction. This permits the finish work for the cement and plaster stages of the pool construction to be effected without the danger of cement or plaster getting into the fitting during construction. After construction has been completed, the cap is released and drops away, carrying with it any cement or plaster which may have hardened on it during construction.
