Abstract
A threaded U-bolt receives a conduit to be clamped to an I-beam. A moisture resistant, polymeric material covers the conduit support portion of the U-bolt with the bolt threads remaining exposed. A clamping member covered with a moisture, resistant polymeric coating includes a first end portion adapted to engage a flange of the I-beam and a second end portion adapted to engage the conduit. A pair of apertures extend through the clamping member. A pair of resilient polymeric annular flanges extend upwardly from the upper surface of the clamping member and around the apertures. The U-bolt threaded ends extend upwardly through the apertures. A pair of polymeric nuts engage the threaded ends above the annular flanges of the clamping member. A resilient sealing flange extends radially from the open end of each encapsulated nut. The nuts are threadedly advanced on the U-bolt threaded ends to position the sealing flanges in contact with the clamping member annular flanges to form a radial, moisture resistant seal around the connections of the nuts to the threaded ends to prevent corrosion of the threaded connections.
