Panduit CLT38N-C630 Corrugated Loom Tubing

The Panduit CLT38N-C630 is a 100-foot corrugated loom tubing designed for cable harness protection in commercial security, automation, and AV installations where abrasion resistance and impact protection are mandatory. Heat-stabilized Nylon 6 construction handles continuous operation up to 230°F (110°C)—critical in equipment rooms with high-density PoE switches, near rooftop HVAC equipment, or in parking structure camera runs exposed to summer heat buildup. The slit-wall design allows retrofit onto pre-terminated cables without connector removal or re-punching—thread the cable through the slit, close it, and secure with cable ties. Inside diameter of 0.421 inches accommodates bundled Cat5e, Cat6, coax, and 18 AWG power conductors in a single protective sleeve.

Key Features

100-foot continuous length reduces splice points in long runs from IDF to camera or access control panel

Slit wall design for tool-free installation on terminated cables—no connector disassembly required

Heat-stabilized Nylon 6 rated to 230°F (110°C) continuous, 50°F higher than standard tubing

0.421-inch inside diameter fits bundled Cat5e/Cat6/coax/power in mixed-cable harnesses

UL 94 HB flammability rating meets NEC Article 725/800 for general indoor wiring

Corrugated profile provides crush resistance against impact and mechanical stress

Black finish maintains professional appearance in exposed installations

RoHS compliant for lead-free installation requirements

Heat stabilization extends the thermal operating range of standard Nylon 6 from 180°F to 230°F—necessary in equipment racks with multi-port PoE++ switches pushing 90W per port, near building automation controllers with dense processor loads, or in attic spaces where summer temperatures exceed 150°F ambient. The corrugated profile maintains flexibility for routing through j-hooks and cable trays while providing crush resistance when cables pass through metal studs, sharp-edged rack knockouts, or conduit transitions. Wall construction absorbs impact from tools dropped during adjacent work, prevents rodent damage in crawl spaces and parking structures, and resists abrasion in high-vibration environments like industrial control panels. The slit runs the full 100-foot length, so you can open the tubing at any point to branch cables without cutting—critical when adding a device to an existing harness or troubleshooting a single conductor.

Common deployment scenarios include protective sleeving for IP camera drops in parking structures where cables run exposed along beams and columns, harness protection in access control installations where door strikes and card readers share a single conduit pathway, and retrofit protection in existing installations where re-termination would require taking systems offline. Secure the tubing every 18 to 24 inches with Panduit Pan-Ty cable ties or equivalent to prevent sag and maintain bundle integrity—loose tubing collects dust and creates snag points during future work. The 0.38-inch nominal size (0.421-inch inside diameter) handles typical IP camera bundles: one Cat6 data cable, one 18/2 power pair, and one RG59 coax for analog backup, all protected in a single sleeve. For larger bundles or higher conductor counts, step up to Panduit's 0.50-inch or 0.75-inch variants.

UL 94 HB flammability rating meets NEC Article 725 (Class 2/3 circuits) and Article 800 (communications circuits) requirements for general-purpose indoor wiring when used in non-plenum spaces. For plenum installations above drop ceilings, use Panduit's plenum-rated sleeving or route cables in EMT/flex conduit. RoHS compliance ensures lead-free construction for installations in facilities with California Proposition 65 disclosure requirements or international projects requiring REACH conformance. The CLT38N-C630 ships as a single 100-foot coil, sufficient for a typical four-camera branch from an IDF or a main trunk run in a small commercial facility. Stock alongside cable ties, j-hooks, and your standard cable inventory for on-site harness repairs and retrofit protection work.
