Panduit CLT150F-X4 Corrugated Loom Tubing, Slit-Wall, 1.58" ID x 10 ft, Yellow

The Panduit CLT150F-X4 is a slit-wall corrugated loom tube in yellow polyethylene that protects wire bundles and pre-assembled harnesses from crush impact and abrasion. At 1.58" (40.0 mm) inside diameter and 10 feet (3.05 m) in length, it covers substantial cable runs in a single piece — reducing the number of cuts, joins, and potential weak spots in a protection scheme. The slit runs the full length, so you can snap it onto a pre-routed harness without disconnecting anything on either end. If you're routing new cabling in a panel, enclosure, or wire tray, consider pairing it with wire routing and management accessories from the same product family for a complete protection scheme.

Key Features

• Slit-wall design for retrofit installation: The lengthwise slit means the tubing opens and snaps over an existing wire bundle or finished harness. You don't need to thread cables end-to-end, which matters when connectors are already crimped or devices are already wired. This cuts installation time significantly on retrofit and maintenance jobs.
• 1.58" (40.0 mm) inside diameter: Sized for medium-to-large bundles — practical for multi-conductor runs, grouped low-voltage security cables, or grouped AC/DC wiring in an enclosure. Verify your bundle's outer diameter before ordering; too large an ID and the tube won't stay snug without cable ties at close intervals.
• 10 ft (3.05 m) per piece, 1 piece per package: One piece covers a full equipment rack height or a typical intra-panel run without a mid-span splice. For longer continuous runs, plan your joints carefully — abutting pieces with a small overlap and securing both ends with cable ties maintains continuity of protection.
• Crush impact and abrasion resistance: The corrugated profile distributes compressive loads across multiple ribs rather than a flat surface, so foot traffic, pinched conduit edges, and mechanical contact don't concentrate stress at a single point. This is the primary protection mechanism — not just chafe resistance but structural crush resistance.
• UL 94 HB flammability rating: HB (Horizontal Burn) is the baseline UL 94 classification — the material self-extinguishes or burns slowly under the test conditions. This satisfies general-purpose indoor wiring applications. Note: if your installation requires a more stringent flame rating (V-0, V-1, V-2), this tubing does not meet those tiers — specify accordingly.
• Maximum operating temperature 122°F (50°C): Polyethylene softens well above 50°C, but the rated maximum for this application is 50°C. In enclosed electrical panels, near heat-generating equipment, or in unconditioned outdoor spaces in warm climates, verify the ambient temperature won't approach this limit. Indoor, climate-controlled environments are the intended application.
• Yellow color for visual identification: Yellow is a convention for cautionary or warning-adjacent wiring in many facility and industrial standards. In a mixed-color cable management scheme, yellow tubing stands out immediately during troubleshooting or maintenance — useful in security panels, AV racks, or access control enclosures where you want to distinguish circuit groups at a glance.
• Polyethylene construction: PE is chemically resistant to most common cleaning agents, oils, and mild solvents encountered in commercial and light industrial environments. It won't corrode, and unlike some braided sleeving materials, it maintains its form under repeated handling.
• RoHS compliant: Meets the EU Restriction of Hazardous Substances directive — relevant for installations subject to EU environmental regulations or for integrators supplying end-customers with RoHS documentation requirements.
• Secure with cable ties and accessories: The slit design requires external retention — cable ties spaced along the run keep the tube closed and prevent the bundle from working free. Plan for tie placement every 12–18 inches on runs subject to movement or vibration; wider spacing is acceptable on static, horizontal runs.

Integration and Compatibility

The CLT150F-X4 (often searched as CLT150F X4) is part of Panduit's corrugated loom tubing line, which includes multiple inside-diameter sizes and colors — making it straightforward to specify a consistent system across cable groups of different bundle diameters. It is compatible with standard nylon cable ties and Panduit's own cable tie accessories for closure. No special tools are required for installation beyond a utility knife if trimming to length. This tubing is suited for indoor cable protection and management applications including security system panels, access control wiring enclosures, AV equipment racks, industrial control panels, and low-voltage structured wiring installations. Competitor cross-references from the source data include CMRF-CP, 027-2902-0020, and FGS-MIDY-10F for procurement teams evaluating equivalent products.

Frequently Asked Questions

Q: What is the inside diameter of the CLT150F-X4?

A: The CLT150F-X4 has an inside diameter of 1.58 inches (40.0 mm). Measure your cable bundle's outer diameter before ordering to confirm fit — the bundle should be smaller than 1.58" for the tube to close properly with cable ties.

Q: Is the CLT150F-X4 suitable for outdoor use?

A: No. The CLT150F-X4 is rated for indoor applications only, with a maximum temperature of 122°F (50°C). Outdoor environments subject the tubing to UV exposure and wider temperature swings that exceed its design parameters.

Q: What flammability rating does the CLT150F-X4 carry?

A: It carries a UL 94 HB (Horizontal Burn) rating. This is the baseline UL 94 classification, appropriate for general-purpose indoor wiring. If your installation requires V-0, V-1, or V-2 ratings, this product does not qualify — select a higher-rated loom tubing.

Q: Does the CLT150F-X4 need any special tools for installation?

A: No. The slit-wall design allows the tubing to snap open and close over an existing wire bundle by hand. A utility knife or scissors can trim it to length if needed. Secure with standard cable ties — no proprietary tools required.

Q: Is the CLT150F-X4 RoHS compliant?

A: Yes. The CLT150F-X4 meets RoHS (Restriction of Hazardous Substances) requirements.

Q: How many pieces are included per package?

A: One piece of 10-foot (3.05 m) corrugated loom tubing is included per package.

Jerry Tildsen

The CLT150F-X4 is a straightforward product, but the 1.58" inside diameter is the spec that determines whether it belongs on your job or not — I've seen installers order a size too small and spend an hour fighting a bundle that won't close, or order too large and end up with a floppy tube that rattles against the panel wall. Measure the bundle OD first, confirm it's under 1.58", and this piece will drop right in.

Technical Highlights:

• 1.58" (40.0 mm) ID: Covers medium-to-large bundles typical in access control and security panels — enough capacity for grouped 18/2, 22/4, and coaxial runs together without forcing them into a smaller tube that stresses the conductors.
• UL 94 HB / 122°F (50°C) max: Fine for climate-controlled server rooms, security head-end rooms, and indoor panel enclosures. Not the right call near heat-generating equipment where enclosure temps can climb past 50°C — polyethylene will soften and lose crush resistance at the wall.
• Full-length slit, 10 ft continuous: Retrofitting over a pre-terminated harness takes seconds — no disconnects, no re-pulling. At 10 feet per piece, one length handles a full rack height or a typical sub-panel to device run in a single unjointed section.

Deployment Considerations:

• Space cable ties no more than 12–18 inches apart on runs with any vertical drop or vibration — the slit will work open under gravity or mechanical movement if ties are too far apart.
• This is an indoor-only product; the 50°C maximum and absence of UV stabilization make it unsuitable for any exposed outdoor run, even in a sheltered location with ambient summer heat.

This tubing is a practical fit for security integrators bundling low-voltage wiring inside access control panels, head-end equipment rooms, or AV racks where a clean, labeled, color-coded cable bundle makes future service calls faster — yellow standing out against black and grey runs in a mixed-circuit enclosure.
