Panduit CLT25F-C4 0.25" 100ft Corrugated Loom Tubing

Panduit CLT25F-C4 Corrugated Loom Tubing

Exposed cable runs in security installations face constant risk from impact damage, abrasion against structural edges, and environmental stress that degrades jacket integrity over time. The Panduit CLT25F-C4 addresses these vulnerabilities with a 100-foot continuous length of split-wall corrugated tubing engineered for retrofit and new-build protection. The 0.281" inside diameter accommodates bundled low-voltage cables commonly found in access control, intrusion, and AV deployments, while the slit wall eliminates the need to disconnect terminations during installation. Yellow coloring provides immediate visual identification for maintenance and compliance documentation in mixed-system environments.

Key Features

• Split-wall design allows installation over pre-terminated cables and assembled harnesses without disconnection
• 0.281" (7.14mm) inside diameter handles typical security/AV cable bundles including 18-22 AWG multi-conductor and coax
• 100-foot continuous length (30.48m) minimizes splicing on long runs between equipment rooms and field devices
• Corrugated polyethylene construction resists crush impact and abrasion from contact with structural members
• UL94-HB flammability rating meets fire-safety requirements for plenum-adjacent and equipment-room installations
• High-visibility yellow color aids tracing, troubleshooting, and compliance with site-specific color-coding standards
• Secures in place with standard cable ties; compatible with Panduit tie-mount accessories for structural attachment
• Operating temperature range up to 122°F (50°C) suitable for indoor mechanical/electrical spaces

The corrugated profile provides flexibility for routing around obstacles while maintaining crush resistance that protects cables from incidental impact in congested pathways. Polyethylene material resists common solvents and cleaning agents encountered in commercial facilities, and the 0.025" nominal wall thickness balances protection with flexibility for tight-radius bends around door frames and through wall penetrations. The slit opens to approximately 0.18" wide, allowing insertion of cable bundles up to the full 0.281" ID without forcing, which prevents jacket damage during installation. Once cables are seated, the corrugated structure naturally closes the slit to maintain protection, and periodic cable ties every 18-24 inches lock the tubing position and prevent longitudinal movement. The yellow color meets ANSI/TIA standards for fiber optic and low-voltage identification in structured cabling systems, making it particularly valuable in mixed-infrastructure environments where instant visual differentiation between power, data, and security circuits is critical for safety and maintenance efficiency.

Security integrators typically deploy this tubing in three scenarios: exposed runs along building infrastructure where cables traverse open-web joists or cable tray edges; retrofit upgrades where existing cables need added protection without system downtime; and new installations where the slit wall accelerates rough-in by allowing tubing installation after cable pull but before termination. In access control deployments, the 0.281" ID accommodates a 6-conductor 22 AWG shielded cable plus a separate RJ45 patch cable for reader-to-controller home runs, or bundled request-to-exit sensors and magnetic lock power in a single protected chase. For AV installations, the tubing protects HDMI and USB extender cables in wall cavities and above-ceiling runs where they cross structural members. The 100-foot length covers typical floor-to-floor vertical riser distances in low-rise commercial construction or horizontal runs in open-plan office retrofits without mid-run splicing, reducing potential failure points and labor time. Pair with Panduit's PLT or PRT cable ties at support intervals, and use CLT-series end caps (sold separately) to close tubing terminations at equipment enclosures and prevent dust ingress or cable snagging during future service work.

UL94-HB flammability rating qualifies this tubing for use in cable pathways adjacent to (but not inside) plenum spaces, and the polyethylene formulation is RoHS-compliant for installations subject to environmental procurement standards. The yellow color specifically supports NEC Article 725 and TIA-606-B administration requirements for low-voltage circuit identification, simplifying inspection and reducing the risk of accidental service disconnection during unrelated maintenance. Panduit's corrugated loom system integrates with their broader cable management ecosystem—mount the tubing to J-hooks or cable runway with TY-series ties, transition to PAN-WAY raceway at equipment rooms, and use the same tie gun and tensioning tools across your entire installation for consistent workmanship and reduced tool investment.
