Panduit CLT50F-C3 Corrugated Loom Tubing Slit Wall 0.5" x 100ft Orange

Overview

The Panduit CLT50F-C3 is a slit-wall corrugated loom tubing designed to protect wire bundles and pre-assembled harnesses from impact, crush forces, and abrasion in indoor electrical and low-voltage installations. At 0.5" (12.7mm) nominal diameter with an actual inside diameter of 0.518" (13.16mm), this 100-foot roll covers a solid run of conduit-free cable routing without mid-job splicing. The longitudinal slit lets you snap the tubing over an existing wire bundle or finished harness assembly without pulling conductors through end-to-end — a practical time-saver on panel retrofits and rack cable management work. Orange color aids circuit identification and zoning in installations where color-coding is part of the cable management discipline. The CLT50F-C3 (often searched as CLT50F C3) ships as a single 100-foot roll.

For installers working across wire routing and cable management applications, this tubing fits squarely in the protective sleeve category — it is not a conduit replacement but a flexible abrasion and impact barrier that travels with the bundle.

Key Features

• Slit-wall design: The full-length longitudinal slit means you install the CLT50F-C3 laterally over an existing bundle without re-terminating connectors or pulling wires through from scratch. On a 20- or 30-conductor harness that's already landed, this can cut sleeve installation time from 15–20 minutes to under 2 minutes per run.
• 0.518" inside diameter: Sized for small-to-mid bundles — think 10–20 AWG control wiring, low-voltage signal cables, or a cluster of Cat5/Cat6 runs in a machinery enclosure. Measure your bundle OD before ordering; the slit closes down on the bundle but won't compress conductors if you're within the 0.518" bore.
• 100-foot continuous roll: A single roll handles most panel-to-panel or rack-to-floor runs without a mid-run splice or sleeve joint. At 30.48 meters, it's sized for industrial floor layouts and longer equipment bay runs without needing to buy multiple shorter pieces.
• Polyethylene construction: PE is chemically inert to most facility cleaning agents and light oils, holds its shape under repeated cable movement, and resists the kind of edge-abrasion that degrades thinner braided sleeves over time. It is not a halogen-free alternative — specify accordingly if your project calls for LSZH.
• UL 94 HB flammability rating: This is the baseline horizontal burn rating — suitable for standard indoor applications where flammability requirements don't mandate UL 94 V-0 or V-2. If you're routing inside a plenum space or an air-handling return, check whether your specification calls for a higher flame class before specifying this part.
• Maximum 122°F (50°C) operating temperature: Appropriate for most indoor electrical enclosures and low-heat industrial environments. Not rated for high-heat proximity — keep it away from heat sinks, motor housings, and anywhere sustained ambient exceeds 50°C.
• RoHS compliant: Meets EU Restriction of Hazardous Substances requirements, which matters if the finished equipment ships to EU markets or if your customer's procurement spec mandates RoHS documentation on every BOM line item.
• Orange color coding: Visually separates circuit groups in multi-bundle enclosures — useful in security panel wiring where power, data, and alarm circuits share the same trough and color-coded sleeves are part of the as-built documentation standard.
• Secure with standard cable ties: No proprietary clips or fasteners required. Standard nylon cable ties hold the tubing in place at anchor points, keeping installation tooling requirements to what any technician already carries.

Integration & Compatibility

The CLT50F-C3 is compatible with Panduit's full line of cable management accessories, including Panduit cable tie mounts and adhesive-backed anchor bases for securing the tubing to panel walls or wire trays. The slit design works with standard loom clips and tie-down saddles used across the Panduit wire management ecosystem. For bundling before sleeving, Panduit cable ties in the PLT series are dimensionally matched to work alongside this tubing family.

This part is a direct competitor cross to Hellermanntyton 04-SL.500-O, making it a drop-in substitute on projects specifying that part number. As part of a broader abrasion protection approach, consider pairing with Panduit braided sleeving or spiral wrap for areas where flex cycles are higher or tighter bend radii are required. For runs entering enclosures, Panduit's corrugated tubing fittings provide strain relief at panel knockouts.

Frequently Asked Questions

Q: What is the actual inside diameter of the CLT50F-C3, and what bundle size will it accommodate?

A: The inside diameter is 0.518" (13.16mm). It will accommodate wire bundles up to approximately that diameter. Measure your bundle's OD before selecting — if the bundle exceeds 0.518" when compressed, move up to the next tubing size in Panduit's CLT family.

Q: Is the CLT50F-C3 suitable for plenum or air-handling spaces?

A: No. The CLT50F-C3 carries a UL 94 HB rating, which is the horizontal burn baseline and is not rated for plenum use. Plenum-rated applications require a higher flame classification. Select a plenum-rated sleeve product for those environments.

Q: Can the CLT50F-C3 be used outdoors?

A: The product is specified for indoor applications. For outdoor cable protection, select a UV-stabilized or weather-rated corrugated loom product from Panduit's catalog.

Q: What is the maximum temperature rating for the CLT50F-C3?

A: The maximum temperature rating is 122°F (50°C). This covers most indoor electrical enclosures and light industrial environments, but is not appropriate for high-heat proximity — keep away from motor housings, heat sinks, and areas with sustained ambient temperatures above 50°C.

Q: Is the CLT50F-C3 RoHS compliant?

A: Yes. The CLT50F-C3 meets RoHS (Restriction of Hazardous Substances) requirements, making it suitable for inclusion on equipment BOMs destined for EU markets or projects requiring RoHS documentation.

Q: How is the tubing held in place after installation?

A: The slit tubing is secured with standard cable ties and compatible cable management accessories. No proprietary fasteners are required — standard nylon cable ties work at anchor points along the run.

When I spec corrugated loom tubing on a security panel retrofit, the slit design is the detail that actually matters on the job. The CLT50F-C3's 0.518" inside diameter and full-length slit let a technician dress a pre-landed 15-conductor harness in under two minutes — no pulling wires back through from scratch, no connector re-termination. That's the practical reason this SKU shows up repeatedly on panel modernization work where time on-site is the real cost driver.

Technical Highlights:

• 0.518" inside diameter: Accommodates typical low-voltage security bundles — a cluster of 18 AWG alarm conductors or a grouping of Cat6 home-run cables sits cleanly inside without pinching. Know your bundle OD before committing to this size.
• 100ft continuous roll: Covers 30.48 meters without a mid-run splice. For a standard equipment room with multiple panel-to-rack runs, one roll typically handles 3–5 dressed runs depending on routing length.
• UL 94 HB + 122°F (50°C) max temp: Clears the bar for standard indoor electrical environments but draws a hard line at high-heat proximity. I keep it away from anything that runs warm — power supply housings, transformer enclosures, and UPS units.

Deployment Considerations:

• Orange is useful as a zoning color in mixed-signal panels — assign it to one circuit class (e.g., power feeds) and use Panduit's other CLT color variants for data or alarm circuits so your as-built documentation maps directly to what's visible in the enclosure.
• The UL 94 HB rating is the ceiling here — if a job spec calls for UL 94 V-0 or V-2, or if the run enters a plenum return, this part is the wrong choice and substituting it is a code compliance issue, not just a preference.

The CLT50F-C3 is the right call on indoor security panel retrofits and equipment bay harness dressing where pre-assembled bundles need protection and the install team can't afford re-termination time. It is not the spec for outdoor runs, high-heat enclosures, or plenum paths — those need a different product entirely.
