Filed under: Cable Pulling, Raceway, Duct and Conduit
I’ve never thought of simple, innocent conduit as being gross. It keeps cables safe, takes them from one place to the next… and that’s it, right? Not if you also factor in the possibility that something other than cables and air could weasel its way into a stretch of conduit. Dirt and general debris (annoying, but not too terrible). Sticky cable lubricant residue (gross). And then of course, the really fun stuff like dead insects and (gulp) animal droppings (a “@*&$#*%^!!!!” would not be out of line here). “Nasty” would be the understatement of the decade.
Now that you know the truth about what could be lurking inside your conduit, the big question is how to get it out. It’s not like you can stick a pressure washing wand down that stuff – but that would be nice, wouldn’t it? Luckily, Ideal Industries got creative and came up with a very cool little thing called a foam carrier, a plug-like cleaning tool that’s attached to a pull line or cable, and maneuvered through a length of conduit – in one end, and out the other. As it’s pulled through, the foam carrier gently scrapes out any nasty bits that are clinging to the conduit’s interior, leaving you with a clean, unobstructed run of duct to send new cables down.
Being made of foam, the carriers are mildly flexible, so they can navigate smoothly through bends and around corners. You can pull them by hand, or even better, use a mechanical blower or vacuum system to send them down the line. Want to cut time in half and clean your conduit while you’re running new cables? Each foam carrier features a metal center rod, which is equipped with hooks at each end, perfect for attaching to, say, cabling. Once the cables and carrier are attached, just pull the whole assembly at once, and you’ll have freshly-pulled wires in crud-free conduit. That’s what I’m talking about.
