To avoid the above situation, ensure any conduit from equipment to a display measures 1.5” in diameter, or 2” if you want maximumflexibility. I personally recommend Carlon flexible raceway. It’s available inmultiple diameters, is flexible enough to be easily installed and roundcorners, and supports a host of accessories. Carlon makes couplers to connecttogether two lengths of conduit, clamps to hold conduit in place, and couplersto secure the conduit to a low voltage work box.
You don't need to run a pull string, or pull line, through the conduit at the time of install, but it's a good idea. You can purchase a 500' spool for about $10. Tie a small plastic bag to the end of the string and use a vacuum to pull it through the conduit. This works much better than messing with steel or fiberglass fish tape.
