Panduit CLTS25F-C Corrugated Polyethylene Loom Tubing, 100 Ft

Overview

The Panduit CLTS25F-C is a 100-foot roll of solid corrugated loom tubing — black polyethylene, 0.281-inch inside diameter — built for bundling and protecting wire runs in control panels, cable trays, and equipment enclosures where abrasion and routing stress are daily realities. If you are routing low-voltage runs behind panels or through conduit pathways and need flexible, split-free protection that won't degrade under moderate heat, this is the format to reach for. CLTS25F-C (often searched as CLTS25F C) ships as a single 100-foot pack, so one roll typically handles a full rack or cabinet wiring job without cutting into a second unit.

Key Features

• 0.281-inch (7.14mm) inside diameter: sized to bundle small wire groups — think 4 to 8 conductors of 22–18 AWG — without forcing the cables into a tight radius that fatigues insulation over time.
• 100-foot continuous roll: enough length to run from a patch panel to the floor and back several times in a standard 42U rack environment, minimizing mid-run splices that create friction points and future troubleshooting headaches.
• Solid wall (non-slit) corrugated construction: the tubing is not pre-split, which means it maintains its cross-section under compression and won't pop open if cables shift or if the bundle is routed through a tight bend. Slit loom is faster to load, but solid tubing holds its shape and stays closed — the right call when cables won't be added or removed after installation.
• Polyethylene material: chemically resistant to the cleaning solvents and contact sprays common in industrial and data center environments; won't crack or craze on contact with isopropyl alcohol or light lubricants the way PVC conduit occasionally does.
• UL94-HB flammability rating: meets the horizontal burn classification under UL94 — appropriate for general wiring applications inside enclosures that themselves carry a higher fire rating. Understand that HB is the base UL94 tier; if your installation calls for V-0 or V-2 (vertical flame), you will need to specify a different material.
• Maximum operating temperature of 122°F (50°C): covers most indoor panel environments, including those with modest heat buildup from active networking gear. Not rated for high-heat zones adjacent to power distribution equipment running sustained loads above that threshold.
• Black colorway: absorbs minor soiling and blends with standard black cable management hardware — keeps installs looking intentional rather than patchwork.

Integration and Compatibility

The CLTS25F-C is compatible with standard cable loom clips, tie mounts, and corrugated tubing fittings sized for 0.25-inch nominal tubing. It works alongside structured cabling accessories and fits within Panduit's cable management ecosystem, including their cable ties, mounting bases, and cable management trays. For installations requiring split-loom access — where wires are added post-installation — consider Panduit's CLTS series in slit variants. If thermal or flame requirements exceed UL94-HB, evaluate nylon or polypropylene corrugated options in Panduit's loom tubing line rated V-0.

Frequently Asked Questions

Q: What wire gauge range fits inside the CLTS25F-C?

A: The 0.281-inch (7.14mm) inside diameter accommodates bundles of small conductors — generally 22 to 18 AWG in groups of 4 to 8, depending on insulation thickness. Always verify your fill ratio before committing to a roll.

Q: Is the CLTS25F-C a slit or solid loom tubing?

A: Solid (non-slit). The tubing must be loaded from one end. This makes it more secure for permanent installations but means wires cannot be added after the fact without re-threading. If you need post-installation access, look at slit variants in the same Panduit CLTS family.

Q: What is the flammability rating of the CLTS25F-C?

A: UL94-HB — the base horizontal burn classification. This is suitable for general enclosure and panel wiring but does not meet the more stringent V-0 or V-2 vertical flame ratings. Check your project specifications before substituting.

Q: What is the maximum temperature the CLTS25F-C can handle?

A: 122°F (50°C) continuous. Suitable for most indoor panel and rack environments. Avoid routing adjacent to heat-generating power equipment that sustains temperatures above that threshold.

Q: How much tubing is included in one unit of CLTS25F-C?

A: One 100-foot (approximately 30.5 meter) roll per pack. One roll is typically sufficient for a full rack or medium-density cabinet wiring run.

The CLTS25F-C comes up often in panel wiring and low-voltage security installs where someone needs a solid, corrugated sleeve that won't unzip at a bend. The solid-wall construction is the detail that matters most here — it keeps the 0.281-inch bore consistent through tight routing paths, which slit tubing simply can't guarantee once the bundle flexes under load.

Technical Highlights:

• 0.281-inch ID: lands in the sweet spot for small multi-conductor bundles; tight enough to keep cables organized, wide enough to thread without forcing conductors against each other.
• UL94-HB flame rating: meets horizontal burn requirements for general enclosure applications — confirmed for this polyethylene construction; do not spec it where the AHJ requires V-0.
• 50°C maximum temperature: covers the ambient ceiling in most active networking and low-voltage panels; exceeding this threshold will begin to soften the polyethylene corrugation and reduce its protective cross-section.

Deployment Considerations:

• Because this is solid (non-slit), pre-plan your wire bundle before threading — fishing conductors through 100 feet is straightforward, but retrofitting a single added wire later means pulling the whole bundle back out.
• Polyethylene is chemically resistant to most field sprays but has a relatively low max temperature of 122°F — verify panel heat load before specifying in enclosures with dense active electronics running near capacity.

The CLTS25F-C is the practical pick for security system control panel wiring, camera homerun bundles in conduit, and access control low-voltage runs where a clean, durable sleeve beats bare cable ties and nothing else.
