Carlon A9D2S1JNNB250 – Frequently Asked Questions

1) What size cable can I pull through 1-1/2 inch Carlon corrugated innerduct?
The Carlon innerduct is a 1-1/2 inch nominal size duct, so the usable inside diameter is smaller than 1-1/2 inches once the corrugation profile is accounted for. Nominal sizing is how conduit and duct is called out on a drawing, not a measured bore. Match your cable bundle to a 1-1/2 inch nominal duct and pull accordingly. For heavier bundles, step up to a larger nominal innerduct rather than forcing the pull.
2) Can Carlon HDPE innerduct be direct buried underground?
High density polyethylene is the standard material for buried duct work because it resists soil chemicals and moisture and stays flexible in a trench. The Carlon corrugated innerduct is built from polyethylene and is used for underground cable protection, commercial building infrastructure, and utility distribution. The corrugated wall lets it follow trench bends and route around obstacles without fittings at every turn.
3) What reel and coil lengths does the Carlon 1-1/2 inch innerduct come in?
Nine ordering options across six lengths: 250 ft (plain, coil, or packed in a box), 500 ft (plain, coil, or packed in a box), 1,000 ft, 2,200 ft, and 2,900 ft. The short lengths give you a choice of how it arrives, coiled or boxed, which matters if you are carrying it into a building rather than setting a reel at a trench. The long lengths are single continuous runs, so a 2,900 ft reel pulls a full run with no coupling in the middle.
4) Why is this innerduct orange, and does the color mean anything on a jobsite?
Orange is the color of the duct itself, and on a jobsite the color is how crews tell one carrier's or one system's duct apart from another in a shared trench or a crowded manhole. The Carlon 1-1/2 inch corrugated innerduct is orange throughout, so a cut end or an exposed run reads the same as the reel. If your spec or utility standard calls for a different color to identify a circuit type, this one will not satisfy it.
5) What is the manufacturer part number for the 1,000 ft reel of Carlon orange innerduct?
The 1,000 ft reel is Carlon part A9D2S1JNNB1000. The 2,200 ft reel is A9D2S1JNNB2200 and the 2,900 ft reel is A9D2S1JNNB2900. Those are the three long-reel part numbers, and the trailing digits are the footage, so a submittal or a purchase order reads unambiguously as to length.
6) Is corrugated innerduct the right choice, or should I use smoothwall duct?
Corrugated innerduct is the flexible option. The ribbed wall bends around obstacles and follows a trench or a riser without needing sweeps and fittings at every direction change, which is why it goes in fast on long underground and building runs. Smoothwall duct is stiffer and the smooth bore favors long straight pulls with less friction. If your route has bends and you want to pay them off in flexibility rather than fittings, the corrugated 1-1/2 inch is the one; if you have a straight shot and a long, heavy pull, look at smoothwall.
7) Is Carlon innerduct made in the USA for a Buy American job?
Country of origin on the Carlon corrugated innerduct is the United States. On federally funded work with a domestic sourcing requirement, that is the line your submittal needs, and it applies across the reel and coil lengths since they are the same product in different put-ups.
8) Can I use HDPE innerduct for fiber optic and telecom cable, or is it only for power?
Telecommunications cable routing and data center cable management are among the uses for this duct, along with industrial wiring and municipal infrastructure. Innerduct is a pathway, not a raceway rated to carry a specific conductor, and the polyethylene body isolates and protects whatever runs inside it. For fiber, the corrugated wall is what lets you route it around structure without adding pull tension at every bend.
9) Should I order the 250 ft coil or the 250 ft box of innerduct?
Same duct, different packaging. The coil is the bare put-up, quicker to pay out at a trench or a manhole. The box keeps the coil contained, which is what you want when the material is going up an elevator, across a finished floor, or into a data center where a loose coil is a hazard and a mess. Both are offered at 250 ft and at 500 ft, so pick on how the material gets handled once it hits the site.
10) Will chemicals or moisture in the ground break down HDPE innerduct?
High density polyethylene is chosen for buried and industrial duct precisely because it does not corrode and holds up against the chemicals and moisture found in soil. The Carlon 1-1/2 inch innerduct is polyethylene, which is what makes it suitable for the underground and industrial facility work it is used on. Nothing to coat, nothing to paint, no galvanic issue where it crosses other buried metal.
