Panduit CLT188F-C4 Corrugated Loom Tubing, Slit Wall, 1.87" ID, 100ft Yellow

Overview

The Panduit CLT188F-C4 is a 1.87-inch (47.5mm) inside-diameter slit-wall corrugated loom tube designed to protect wire bundles and pre-assembled harness assemblies from impact, crush forces, and abrasion. Supplied in a 100-foot (30.4m) roll of yellow polyethylene, this is a practical go-to for wire routing and cable management in panel builds, machine wiring, and control cabinet applications where dressing cables neatly and protecting them from chafing matters. The slit running the full length of the tube is the key installation feature — you can drop an existing harness into the loom without threading wires end-to-end, cutting installation time considerably on retrofit and service calls. Secure the dressed bundle with Panduit cable ties and accessories once routed.

Key Features

• Slit-Wall Construction: The full-length slit lets you install CLT188F-C4 over a pre-assembled wire harness or a live bundle without disconnecting connectors — a real productivity gain on panel retrofits and service jobs where re-terminating is not an option.
• 1.87-Inch (47.5mm) Inside Diameter: Sized for larger wire bundles and cable groups — enough room to consolidate multiple conductors, control wiring, or sensor cables into a single protected run without forcing wires into an undersized sleeve.
• 100-Foot (30.4m) Continuous Roll: A full 100ft per roll means you can cover long unbroken cabinet runs or tray sections without splicing sections together. One roll, one purchase, no mid-run seams.
• Polyethylene Construction, UL 94 HB Rated: Polyethylene provides genuine abrasion and crush resistance where cables route through panel edges, past hardware, or through corrugated enclosure knockouts. UL 94 HB is the accepted horizontal burn standard for general industrial wiring environments — appropriate for the indoor applications this product targets.
• 122°F (50°C) Maximum Temperature: Rated for continuous use up to 50°C — covers typical indoor panel and control cabinet environments. If your installation sees higher sustained temps (near heat sources, direct-sun enclosures), verify ambient before specifying; this is an indoor product.
• Yellow Color for Visual Identification: Yellow is a recognized convention for caution-flagged, high-voltage, or dedicated-circuit wiring in many industrial facilities. Using CLT188F-C4 for a specific cable category makes it immediately distinguishable during service and inspection without labeling every inch of the run.
• RoHS Compliant: Meets RoHS requirements — relevant for equipment destined for EU markets or facilities with environmental compliance programs that restrict hazardous substances in electrical components.
• Cable Tie Compatible: Designed to be secured with standard Panduit cable ties and accessories. No special tooling or proprietary fasteners needed — work with the ties and mounts already in your inventory.

Integration & Compatibility

The CLT188F-C4 is a passive mechanical protection product — it works with any wire type, gauge, or system. Pair it with cable management accessories including Panduit cable ties, edge clips, and mounting hardware to complete a dressed, serviceable installation. The 1.87-inch ID suits substantial wire bundles; for smaller harnesses, consider narrower CLT series variants. For installations requiring UL-listed conduit or higher flame ratings, evaluate the appropriate Panduit conduit or braided sleeving options from the Panduit wire protection catalog. This product is specified for indoor use — not rated for direct outdoor exposure or wet/submerged environments.

Frequently Asked Questions

Q: Can the CLT188F-C4 be used outdoors?

A: No. The CLT188F-C4 is specified for indoor applications only. The polyethylene material and UL 94 HB flammability rating are appropriate for enclosed, climate-controlled environments. For outdoor or wet-location cable protection, a product with a suitable outdoor/UV rating would be required.

Q: What is the inside diameter of the CLT188F-C4?

A: The inside diameter is 1.87 inches (47.5mm). This is a large-bore loom tube suited for substantial wire bundles or grouped cable assemblies.

Q: How is the CLT188F-C4 installed over an existing harness?

A: The slit running the full length of the tube allows you to open the loom and snap it around an existing wire bundle or pre-assembled harness without disconnecting any connectors. Once dressed, secure it in place using standard cable ties or Panduit accessories.

Q: What is the maximum operating temperature for the CLT188F-C4?

A: The maximum continuous temperature rating is 122°F (50°C). This covers most standard indoor panel and control cabinet environments. Applications near sustained heat sources above 50°C ambient should be evaluated separately.

Q: Is the CLT188F-C4 RoHS compliant?

A: Yes. The CLT188F-C4 meets RoHS compliance requirements, making it suitable for installations and equipment builds destined for markets with RoHS restrictions on hazardous substances.

Q: How much loom tubing is included per package?

A: One package contains a single 100-foot (30.4m) roll of slit corrugated loom tubing.
