Panduit CLC88X3S8C370 Heavy-Duty Corrugated Loom Tube Clamp
Overview
The Panduit CLC88X3S8C370 is a heavy-duty, three-position corrugated loom tube clamp engineered specifically for securing 7/8-inch corrugated loom tubing in industrial wire routing and cable management applications. Supplied in a convenient 100-piece package, it is the right fastener when you need consistent, repeatable clamp placement across control panels, machine enclosures, or structured cabling runs where loose tubing causes vibration fatigue or inspection failures. Panduit's wire management catalog covers the full spectrum of corrugated loom accessories, and this clamp fits squarely in the middle of that ecosystem.
Key Features
- Nylon 6.6 Construction: Nylon 6.6 handles continuous exposure to industrial solvents, oils, and moderate heat better than standard nylon 6 — meaning these clamps won't become brittle and crack out of a panel two years after install. That matters on any cable conduit and support application where re-entry is disruptive.
- Three-Position Mounting: Three mounting positions on a single clamp give you flexibility to align tubing runs at different angles or heights without stocking multiple part numbers. In tight conduit trays or densely wired enclosures, that adjustability eliminates the awkward offsets you'd otherwise route around.
- Compact Footprint (1.1 in. W × 0.7 in. H × 4.3 in. L): At 28 mm wide and 18 mm tall, the CLC88X3S8C370 fits inside standard DIN-rail enclosures and shallow wireway channels without consuming the clearance you need for adjacent conductors. The 4.3-inch length provides a stable clamp surface that resists rocking under vibration.
- Purpose-Built for Corrugated Loom: This clamp is designed specifically for corrugated loom tubing — not smooth conduit, not split loom. The mating geometry seats the corrugated ribs positively so the tube doesn't walk or rotate under flex cycles. Using a generic cable clamp on corrugated loom typically results in the tube sliding out of position over time; this part eliminates that failure mode.
- 100-Piece Pack Quantity: The 100-piece package quantity matches the scale of a panel build or mid-size machine wiring job without forcing you into a 500-count carton. If your project scope grows, the 500-count carton (also available) brings per-unit cost down for volume work.
- Black Color, Catalog-Standard: Black Nylon 6.6 is the industry default for industrial enclosures — matches standard wire duct and wireway, keeps your panel looking consistent for customer or inspector walkthroughs.
Integration & Compatibility
The CLC88X3S8C370 is compatible with 7/8-inch (nominal) corrugated loom tubing. Verify your loom outside diameter against the 7/8-inch clamp bore before ordering — Panduit produces clamps across multiple tubing sizes and the fit is not adjustable. This clamp pairs naturally with Panduit corrugated loom products and standard panel-mount hardware. For broader cable management planning guidance, including tubing sizing and routing best practices, consult Panduit's wiring system documentation. Complementary hardware such as cable ties and mounting screws are sold separately.

Frequently Asked Questions
Q: What tubing size does the CLC88X3S8C370 fit?
A: The CLC88X3S8C370 is designed for 7/8-inch corrugated loom tubing. Confirm your tubing's outside diameter matches before ordering — Panduit produces this clamp family in multiple sizes and the bore is fixed.
Q: What material is the CLC88X3S8C370 made from?
A: It is molded from Nylon 6.6, which provides better chemical and heat resistance than standard Nylon 6 — suitable for industrial enclosures, control panels, and machine wiring environments.
Q: How many clamps are included in one order?
A: One package contains 100 clamps. A 500-count carton quantity is also available for larger project volumes.
Q: What are the physical dimensions of the CLC88X3S8C370?
A: The clamp measures 1.1 inches (28 mm) wide, 0.7 inches (18 mm) tall, and 4.3 inches long — compact enough for most standard DIN-rail enclosures and wireway installations.
Q: Can this clamp be used with smooth conduit or split loom?
A: No. The CLC88X3S8C370 is engineered specifically for corrugated loom tubing. Its mating geometry matches the corrugated rib profile; it is not intended for smooth conduit, liquid-tight fittings, or split loom applications.
The CLC88X3S8C370 is one of those parts that panel builders tend to underspec until they've had a loom tube vibrate out of a clamp mid-production run. The Nylon 6.6 construction and the corrugated-specific bore geometry are what separate this from a generic cable clamp — and at 4.3 inches in length with a three-position mounting body, it gives you options in cramped enclosures that a single-position clamp simply doesn't.
Technical Highlights:
- Nylon 6.6 vs. Nylon 6: Nylon 6.6 has a higher melting point and better resistance to petroleum-based fluids — relevant in machine tool and automation enclosures where cutting fluid mist or hydraulic vapor is present. This is not a cosmetic material upgrade.
- Three-Position Body (4.3 in. L): The 4.3-inch body length gives a stable engagement zone that resists the rocking motion that loosens clamps under continuous vibration. Three-position adjustability means one SKU covers slight routing variations across a panel build — you're not hunting for a different part number mid-job.
- Compact Cross-Section (1.1 in. W × 0.7 in. H): At 28 mm wide and 18 mm tall, this clamp fits in standard 2-inch wireway without consuming the clearance reserved for conductor bends. That matters when you're routing both loom and loose conductors through the same channel.
Deployment Considerations:
- Match clamp bore to actual loom OD before ordering — the 7/8-inch designation is nominal. Measure your specific loom product; aftermarket corrugated loom ODs vary by manufacturer and a loose fit will not hold under vibration.
- The 100-piece pack (versus the 500-count carton) is the right buy for a single panel build or small machine run; for production-line quantities, the 500-count carton reduces per-unit cost and warehouse handling touches.
The CLC88X3S8C370 is the correct call for industrial machine enclosures and automation control panels where corrugated loom runs must stay stationary through continuous duty vibration cycles — specifically where Nylon 6 hardware has failed inspection or shown crazing in solvent-exposed environments.
