FITTING FOR ENT TUBING

摘要

A fitting for attaching ENT tubing to a concrete form has an inverted cup-li ke configuration with a bottom opening and an internal cavity within a fitting wall. A flange extends outwardly from the fitting wall around the bottom opening and has fastener-receiving holes for attaching the fitting to a plane surface of a concrete form. A socket extends through the fitting wall into the cavity for receiving an e nd portion of an ENT tube. The socket has a plurality of circumferentially-spaced resilient fingers that are inclined inwardly toward the socket axis for gripping an EN T tube. A pair of opposite fingers have teeth that are receivable in an annular groove in an end portion of a corrugated ENT tube. The teeth have rounded ends to facilitate ratcheting movement of the ENT tube end portion both into and out of the socket.
