Panduit CLT125F-L3 Split Corrugated Loom Tubing, 1.303" ID, 50 Ft, Orange
The Panduit CLT125F-L3 is a 50-foot length of split corrugated polyethylene loom tubing with a 1.303" (33.1mm) inside diameter, sold in orange. The slit-wall design lets you press wire bundles in laterally — no threading from the end — making it a practical choice for retrofitting cable protection on existing wiring runs in panel enclosures, control cabinets, and structured cable pathways. If you're managing Panduit cable management builds or looking to protect multi-conductor bundles without cutting into live assemblies, this is a straightforward answer.
Overview
Corrugated loom tubing like the CLT125F-L3 serves a specific role in installations where cables need abrasion protection and routing organization, but flexible conduit would be overkill. The corrugated polyethylene shell handles moderate bend loads and protects against incidental contact damage without adding significant bulk or rigidity. The orange color provides visual identification — useful in dense panels or multi-zone wire management runs where you need fast visual differentiation between circuit groups. This is a wire management consumable designed for production-volume electrical and AV integration work.
Key Features
- 1.303" (33.1mm) Inside Diameter: sized to accommodate larger wire bundles — multi-conductor power runs, grouped Cat6 home-run cables, or conduit-feed clusters — without forcing tight bends that stress insulation. Verify your bundle's outer diameter against this ID before ordering; the corrugated wall adds roughly 0.15–0.25" to the outside profile.
- 50-Foot Length per Pack: a single CLT125F-L3 covers a full equipment room run or multiple shorter routing paths from a single reel. For projects with longer continuous runs, plan splices at junction points to avoid waste.
- Slit (Split) Wall Construction: the longitudinal slit lets you snap cables into the tubing mid-route. In retrofit scenarios — adding protection to wiring already terminated at both ends — this eliminates the need to disconnect and re-thread, cutting installation time substantially on dense panels.
- Orange Color Code: orange is commonly used to designate low-voltage power circuits or to distinguish specific cable groups in color-coded wire management plans. In security and AV installations, consistent color discipline in enclosures reduces troubleshooting time and mis-termination risk on future service calls.
- Polyethylene Construction: PE loom is chemically inert to most cleaning agents and cutting oils encountered in light industrial environments. It won't absorb moisture or swell, which matters in enclosures subject to condensation or periodic wash-down adjacent areas.
- UL94-HB Flammability Rating: this rating indicates the material will burn when exposed to an open flame but is not self-sustaining — it will extinguish when the flame source is removed. Acceptable for many commercial panel and enclosure applications; if your installation code requires self-extinguishing or flame-retardant cable management, verify local requirements before specifying this product.
- 122°F (50°C) Maximum Operating Temperature: adequate for typical indoor panel environments. Avoid routing this tubing across high-heat zones such as directly above ballasts, transformer windings, or power supply exhaust paths where ambient temperatures may exceed this limit.
Integration and Compatibility
The CLT125F-L3 (often searched as CLT125F L3) is a passive wire management component — it pairs with Panduit's broader cable ties and bundling accessories line, including cable tie mounts and loom clips, to secure routing paths within enclosures. It is compatible with standard corrugated loom fittings and end caps that match the 1.303" ID profile. For installations requiring higher flame resistance or exposure to oils and solvents, Panduit offers alternative loom materials in the CLT family rated to more demanding environmental profiles — confirm the specific variant against your project's code requirements before substitution.
Frequently Asked Questions
Q: What is the inside diameter of the CLT125F-L3?
A: The inside diameter is 1.303 inches (33.1mm). This accommodates moderately large wire bundles; verify your bundle's outer diameter fits within this clearance before ordering.
Q: Is the CLT125F-L3 slit along its length for easy cable insertion?
A: Yes. The CLT125F-L3 features a longitudinal slit (split-wall) design that allows you to press cables in laterally without threading from the end — useful for retrofitting protection on already-terminated wiring runs.
Q: What is the maximum temperature rating for this loom tubing?
A: The maximum operating temperature is 122°F (50°C). Avoid routing near high-heat components such as transformer windings or power supply exhaust paths that exceed this limit.
Q: What is the flammability rating of the CLT125F-L3?
A: It carries a UL94-HB rating, meaning the material will not sustain a flame once the ignition source is removed. If your application requires a self-extinguishing (V-0 or V-2) rating, this product is not the correct choice — consult Panduit's broader loom lineup for flame-retardant variants.
Q: Why is the CLT125F-L3 orange instead of the standard black?
A: Orange enables color-coded wire management in panel and enclosure builds, allowing installers and technicians to visually differentiate circuit groups at a glance. It is commonly used to flag low-voltage power circuits or specific cable categories in structured installations.
Q: How long is one pack of CLT125F-L3?
A: Each pack contains 50 linear feet of corrugated split loom tubing. This is sufficient for a full equipment room run or several shorter enclosure routing paths from a single package.
The CLT125F-L3 comes up regularly in enclosure builds where the wire bundle diameter pushes past the 1-inch mark — the 1.303" ID gives you room to route grouped multi-conductor runs or clustered low-voltage feeders without forcing the tubing into a tight oval that would restrict airflow and stress the jacket. At 50 feet per pack, it's a practical quantity for a single MDF build-out or a run of distribution frames without leaving a partial reel on the shelf.
Technical Highlights:
- 1.303" (33.1mm) ID: comfortably handles grouped Cat6 or multi-conductor power bundles that would choke a standard 1" loom — check your actual bundle OD with a caliper before you cut, since the corrugated wall still adds external profile.
- UL94-HB Flammability: stops burning when the flame source is removed, which satisfies most commercial panel codes; if the AHJ mandates V-2 or better, escalate to a flame-retardant loom variant before the inspection.
- 50°C (122°F) Max Temp: covers typical indoor panel ambient, but keep it away from transformer exhaust paths and dense UPS battery stacks where localized heat can spike well past this ceiling.
Deployment Considerations:
- The slit-wall design is the main time-saver here — on retrofit jobs where cables are already terminated at patch panels or PDUs, you can snap the loom over the bundle mid-route rather than disconnecting anything. On new builds, the slit also speeds up staged installations where cable IDs need to stay accessible during testing.
- Orange is a deliberate spec choice, not just availability — if your panel uses a color standard that designates orange for a different circuit type, order the appropriate color variant to avoid creating a visual conflict that trips up the next technician on site.
The CLT125F-L3 earns its place in MDF/IDF enclosure builds and control-panel wire management runs where bundle diameter exceeds what standard 1" loom handles — particularly in retrofit scenarios where the slit wall pays off in installation hours saved.
