Panduit CLT150F-X20 Corrugated Loom Tubing, Slit, 1.58" x 10 ft, Black

The Panduit CLT150F-X20 is a slit-wall corrugated polyethylene loom tube designed for protecting wire bundles and pre-assembled harnesses from crush impact and abrasion in indoor cable management applications. At 1.58" (40.0 mm) inside diameter and 10 ft (3.05 m) per package, it covers mid-to-large bundle diameters without the need for pre-threading — the longitudinal slit lets you snap it directly onto an existing harness and move on. If you're routing surveillance camera drops, panel wiring, or structured-cabling bundles through exposed conduit runs or cable trays, this is a straightforward mechanical protection solution that installs in seconds rather than minutes.

Key Features

• Slit-wall design for over-existing-bundle installation: The lengthwise slit means you don't have to disconnect and feed wires end-to-end through solid tubing. On a pre-assembled harness — common in surveillance panel builds and AV rack installs — this cuts installation time substantially and eliminates the risk of disturbing terminations during routing.
• 1.58" (40.0 mm) inside diameter: This ID accommodates substantial wire bundles — typical multi-camera homerun runs, multi-pair control cable groups, or bundled power leads in a security enclosure. Verify your bundle's outer diameter before ordering; if your bundle diameter is 35 mm or less with some compliance, this will close cleanly and hold its form.
• 10 ft (3.05 m) per package, single unit: One package gives you a single continuous 10-foot run — useful for a single cabinet-to-floor drop, a short tray segment, or a conduit stub. For longer runs, plan your quantity accordingly — there is no field-splicing that maintains the mechanical protection rating, so order in multiples and butt-join with cable ties at transitions.
• UL 94 HB flammability rating: UL 94 HB is the base horizontal burn classification under the UL 94 standard — the material self-extinguishes or burns slowly enough to pass the horizontal test. Suitable for indoor wiring environments where a flame-retardant (but not zero-halogen or high-spec V-0) material is adequate. Not rated for plenum, riser, or enclosed duct applications — confirm your local code requirements before specifying in those spaces.
• 122°F (50°C) maximum operating temperature: Adequate for most indoor panel rooms, conduit runs, and equipment closets at normal ambient conditions. If your installation is near heat-generating equipment or in a non-air-conditioned mechanical space that sees sustained temperatures above 50°C, select a higher-rated sleeve material. This limit is a hard ceiling from the evidence.
• Polyethylene construction, crush and abrasion resistant: PE corrugated tubing handles the incidental foot traffic, cable tray edge abrasion, and repeated minor impacts common in working equipment rooms. The corrugated profile distributes impact loads rather than concentrating them at one point — meaningful in floor-level runs or anywhere cables pass through a high-traffic area.
• RoHS compliant: Meets the Restriction of Hazardous Substances directive, which matters for projects with EU compliance requirements or enterprise customers with materials restriction policies in their procurement standards.
• Secured with standard cable ties: No proprietary fasteners required. Use any standard cable tie to close the slit and anchor the tubing to a tray, bracket, or conduit clip. This keeps your BOM simple and ensures field personnel can work with what's already on the truck.

Integration and Compatibility

The CLT150F-X20 (often searched as CLT150F X20) is part of Panduit's Panduit wire routing and management line, which includes matching fittings and connectors for corrugated loom tubing. For installations requiring a complete managed pathway, pair with compatible Panduit loom fittings at panel entries or tray transitions to maintain consistent protection end-to-end. This tubing is passive mechanical hardware — it integrates with any cabling system regardless of protocol or vendor. It is appropriate for use in wire routing and cable management applications including security panel builds, low-voltage wiring harnesses, and structured cabling in commercial buildings. For installations requiring complementary cable ties and bundling accessories, standard lashing ties are all that's needed to close the slit and anchor runs. If your project also requires cable management accessories such as raceway or duct, review the full Panduit catalog for system-matched components. See the cable management planning guide for help sizing tubing and selecting the right protection level for your run type.

Frequently Asked Questions

Q: What is the inside diameter of the CLT150F-X20?

A: The inside diameter is 1.58 inches (40.0 mm). Verify your wire bundle's compressed outer diameter is within that range before ordering — the slit will close around the bundle, but oversized bundles won't seat properly.

Q: Is the CLT150F-X20 rated for outdoor or plenum installations?

A: No. The product is rated for indoor applications only. The UL 94 HB flammability rating and the 122°F (50°C) maximum temperature limit make it unsuitable for plenum, riser, or exposed outdoor runs. For those environments, select tubing with an appropriate outdoor UV or plenum rating.

Q: Can I install the CLT150F-X20 over a pre-wired harness without disconnecting cables?

A: Yes — that is its primary design purpose. The longitudinal slit allows you to snap the tubing directly over an existing bundle. Secure the slit closed with standard cable ties after installation.

Q: Is the CLT150F-X20 RoHS compliant?

A: Yes, the CLT150F-X20 meets RoHS (Restriction of Hazardous Substances) compliance standards, making it suitable for projects with EU materials restrictions or enterprise procurement RoHS requirements.

Q: How many pieces come in a package?

A: One package contains a single 10-foot (3.05 m) length of tubing. Plan your run quantities accordingly and order multiples for longer continuous runs.

Q: What is the flammability rating of the CLT150F-X20?

A: The tubing carries a UL 94 HB rating, which is the base horizontal-burn classification under the UL 94 standard. It is flame-retardant for typical indoor wiring environments but is not rated V-0, V-1, or V-2, and is not approved for plenum or riser spaces.

The CLT150F-X20 is a product I reach for specifically when a job has pre-terminated harnesses that need mechanical protection added after the fact — the 1.58" (40.0 mm) ID and longitudinal slit mean you're snapping it over an existing multi-camera homerun bundle in seconds, not reterminating anything. It's polyethylene, corrugated, and rated to 122°F (50°C) indoor max, which covers the vast majority of equipment room and low-voltage panel environments without overspecifying.

Technical Highlights:

• 1.58" (40.0 mm) ID: Fits mid-to-large bundle diameters typical of multi-drop surveillance homerun runs — confirm your bundle OD before specifying, but this size handles most 12–20 conductor grouped runs without issue.
• UL 94 HB flammability: Passes horizontal burn — adequate for standard indoor wiring compartments and cable trays. If the AHJ or spec sheet calls for V-0 or plenum-rated protection, this tubing won't qualify; that's a hard stop to check upfront.
• RoHS compliance: Covers material restriction requirements on commercial and enterprise projects without any additional documentation chasing — it's baked in.

Deployment Considerations:

• The slit closes under cable tie tension, but in high-vibration environments (mechanical rooms, near HVAC equipment), use ties at closer intervals — every 12–18 inches rather than the typical 24 inches — to prevent the slit from working open over time.
• The 50°C (122°F) ceiling is a real constraint: non-air-conditioned IDF closets or wiring runs adjacent to heat-generating UPS or power distribution equipment can exceed this in summer conditions. Verify ambient temperatures before specifying here.

This is the right specification for indoor security panel builds and pre-assembled harness protection on commercial surveillance projects where speed of installation matters and ambient temperatures stay within the rated range — not a substitute for plenum or outdoor-rated protection where code requires it.
