NSI-Bridgeport Concrete Encasable Straight Hub — 1 in., Zinc Alloy
The NSI-Bridgeport CSS-100 concrete encasable hub is specifically engineered for pour-in-place conduit installations where the fitting must be embedded in concrete. The flanged end mounts to a concrete form before the pour, and the threaded open end connects to the raceway. Once the concrete cures and the form is removed, the flange can be punctured to provide a clean, threaded raceway entry point.
