Panduit CLT150F-D4 Yellow Polyethylene Flexible Conduit — 1.5" x 500 ft Roll
Overview
The Panduit CLT150F-D4 is a 500-foot roll of yellow, flexible polyethylene conduit with a 1.550" (39.1 mm) inside diameter — a practical choice for color-coded cable routing in security, low-voltage, and network infrastructure installations where consistent protection and visual identification matter. Yellow coloring makes it easy to designate specific cable types or circuit functions at a glance, reducing the chance of accidental cuts or incorrect terminations during future maintenance. CLT150F-D4 ships as a single roll, so job-site ordering is straightforward: one roll, one part number.
Flexible conduit in this diameter range handles the bulk of cable management runs found in commercial and light industrial environments — camera cable home runs, PoE cabling from patch panels to junction boxes, and structured wiring through finished walls or above suspended ceilings. Panduit's Panduit wiring infrastructure products are a familiar choice among integrators who need predictable material quality without surprises on delivery.
Key Features
- 1.550" Inside Diameter (39.1 mm): Wide enough to pull multiple Cat6 or coax runs simultaneously without exceeding a 40% fill ratio — critical when you're routing a bundle of PoE camera drops through a single conduit path. The 1.860" (47.2 mm) outside diameter is compatible with standard 1.5" conduit fittings and straps, so you won't need to hunt for oddball hardware.
- 500-Foot Roll Length: A full 500 feet per package (sold as a single roll) reduces the number of SKUs you need to order for mid-size jobs. On a 20-camera installation with 25-foot average runs, one roll covers the entire conduit requirement with material left for rework — no partial-roll waste from ordering two 250-foot units.
- Yellow Color Coding: In a rack room or cable tray with conduit from multiple trades, yellow designation lets facilities staff and network cabling teams identify low-voltage or security circuits without tracing every run. Consistent color coding across a campus accelerates troubleshooting and satisfies labeling requirements on some jurisdictional code inspections.
- Polyethylene Construction: PE is chemically resistant, lightweight, and maintains flexibility across a broad temperature range — relevant in attic spaces, parking structures, or exterior-adjacent runs where temperature swings are a factor. Unlike PVC, polyethylene won't crack or become brittle in cold environments, and it won't off-gas plasticizers over time that can degrade cable jacket compounds on long-term installations.
- Single-Roll Packaging (Pkg. Qty: 1): No bulk commitment required. For integrators building per-job material lists, ordering exactly the footage needed keeps project accounting clean. The single-SKU, single-roll format also simplifies receiving and job-box organization on multi-trade sites.
- Flexible Form Factor: Flexible conduit bends around structural obstacles without fittings or offset elbows, which is a real time saver when routing through existing construction. In retrofit camera installations through finished ceilings or walls, this saves hours compared to rigid EMT runs that require precise measurement and coupling at every direction change.
Integration & Compatibility
The 1.550" ID accommodates standard 1.5" nominal conduit fittings. Verify connector and strap sizing against the 1.860" OD when selecting clamps for surface mounting or tray routing. This conduit is appropriate for low-voltage data and signaling cables; confirm local electrical code requirements before routing line-voltage conductors. For PoE switch deployments where cable runs extend to IP cameras or access control readers, this conduit diameter comfortably handles bundles of four to six Cat6 cables within NEC fill guidelines.

Frequently Asked Questions
Q: What is the inside diameter of the CLT150F-D4?
A: The CLT150F-D4 has an inside diameter of 1.550 inches (39.1 mm) and an outside diameter of 1.860 inches (47.2 mm).
Q: How many feet are included per package?
A: Each package contains one 500-foot roll. Package quantity is 1 roll.
Q: What material is the CLT150F-D4 made from?
A: It is constructed from polyethylene, which provides flexibility, chemical resistance, and cold-temperature durability compared to standard PVC conduit.
Q: Why is this conduit yellow?
A: Yellow coloring enables color-coded cable pathway identification — commonly used to designate low-voltage, security, or specific circuit types in multi-trade installations, making future maintenance and inspection faster.
Q: Is the CLT150F-D4 suitable for outdoor or temperature-variable environments?
A: Polyethylene maintains flexibility across a wide temperature range and resists brittleness in cold conditions, making it suitable for attic runs, parking structure installations, and other environments with temperature variation. Verify UV resistance requirements for direct exterior sun exposure.
Q: What fitting size is compatible with this conduit?
A: The 1.860" outside diameter is compatible with standard 1.5" nominal conduit fittings and straps. Confirm fitting specifications against the OD dimension when ordering hardware.
The CLT150F-D4 comes up regularly on mid-size commercial security jobs where the installer needs a consistent, identifiable conduit path for camera home runs — and the 500-foot single-roll format means you can spec it per-job without committing to pallet quantities. The 1.550" ID is the practical sweet spot: tight enough to route cleanly through standard 1.5" hardware, wide enough to pull a four-to-six cable bundle in a single pass without fighting fill ratios.
Technical Highlights:
- 1.550" ID / 1.860" OD: Matches standard 1.5" nominal conduit fittings exactly — no adapter hunting. The dimensional pairing means off-the-shelf straps, grommets, and connectors seat correctly without shimming.
- 500 ft per roll, Pkg. Qty 1: One roll covers a 20-camera installation at typical 25-foot run lengths with material to spare. Single-roll SKU keeps job cost accounting clean — no split-roll waste to reconcile.
- Polyethylene construction: PE stays flexible in cold attic and parking structure environments where PVC would stiffen or crack seasonally, reducing the risk of conduit failure during future pull-throughs or rework.
Deployment Considerations:
- Yellow coding is most useful when you establish a site-wide color convention before rough-in — document it in the as-built so the next technician on site doesn't have to guess what yellow means in your specific installation.
- Verify local code jurisdiction on conduit material requirements before using polyethylene in plenum spaces — PE is not plenum-rated, and substituting it where plenum conduit is required will fail inspection.
The CLT150F-D4 is a strong fit for commercial integrators running structured low-voltage paths in new construction or gut-rehab projects where color-coded conduit zoning is part of the design — specifically where the camera, access control, and data runs need to stay visually separated through shared cable trays or wall cavities.
