The Chief CMA-372 Offset Unistrut Adapter simplifies installation to all styles of 1-5/8" Unistrut/U-Channels. Designed with a 1-1/2" cable management gap, the CMA-372 lets you run cable up through the pole and directly out of the Unistrut Adapter. Installation is quick, and the CMA-372 ships with spring nuts and bolts for attaching to Unistrut/U-Channel. The adapter accepts any length of standard NPT 1-1/2" pipe threaded at both ends, letting you adjust the height to fit your needs.
