A real time saver, Gruber Captive Nut Assembly fits directly onto the modular bowl mold. Then, an eye bolt fits through the polydome and screws directly into the captive nut holding the polydome securely in place. This eliminates the need to bend over and reach under the mold to hold the bolt while you tighten down on the wingnut above the polydome.

The Captive Nut portion of the assembly, once tightened into place, becomes an integral part of the mold. Simple.

Because this assembly is permanently affixed to the drain end of the mold, there is no need for a stem assembly. The polydome attaches with an eyebolt for easy removal. Time and materials are saved for a more efficient production process.

We've got plenty in stock, so call and order a supply.
