Panduit CSB42-150-230-Q Cable Clamp Cushion Sleeve
Overview
The Panduit CSB42-150-230-Q is an individual TPU cushion sleeve engineered for use with metal buckle straps, MLT cable ties, and MS straps in demanding cable management and electrical infrastructure applications. At 42.7mm wide and 274mm (10.8 inches) long, this sleeve slips between a metal cable clamp and the cable bundle it secures, absorbing the mechanical stress that would otherwise concentrate at the clamp edge — the failure mode that causes short-circuit events in tightly bundled power runs. If you're specifying cable routing in industrial panels, raceways, or hostile-environment enclosures where a clamp-induced nick on insulation is a liability, the CSB42-150-230-Q (often searched as CSB42 150 230 Q) is the part that closes that gap.
Key Features
- TPU Construction: Thermoplastic polyurethane gives this sleeve meaningful flex without permanent deformation — it conforms under clamp load and springs back if the assembly is loosened for maintenance. That matters on cable runs that get re-accessed in the field, where a brittle sleeve would crack and need replacement.
- 42.7mm (1.68 in) Width: Sized to match the bearing surface of compatible Panduit metal cable clamps and MLT tie widths in this range — the sleeve covers the full contact zone so no bare metal edge contacts the cable jacket. Confirm your clamp's width before ordering; a sleeve that's narrower than the clamp leaves exposed edges that defeat the purpose.
- 274mm (10.8 in) Length: Long enough to wrap bundles with a meaningful overlap on the closure, accommodating bundle diameters up to 70mm maximum — that's roughly a 2.75-inch bundle, which covers most medium-density power distribution runs and conduit bundles.
- 2.5mm Profile Height: The sleeve adds only 2.5mm (0.1 in) of radial thickness to the assembly. In tight cable trays and conduit entries where every millimeter of clearance is budgeted, that slim profile means you can retrofit cushion protection without replanning the layout.
- Individual / Discrete-Length Design: Each sleeve is pre-cut and self-contained — no cutting to length in the field, no shared-stock sleeves that get trimmed unevenly. On a large panel installation with 25 clamp points, consistent sleeve length means consistent assembly quality across every tie point.
- Auto-Close Design: The sleeve wraps and holds position during assembly without requiring a separate hand to keep it in place — relevant on overhead or confined-space installations where you're working with limited reach.
- Short-Circuit Protection Use Case: Designed specifically for applications where a cable clamp failure or insulation breach could cause a short circuit. The cushion layer mechanically isolates the metal clamp from the cable jacket, reducing the probability that clamp vibration or thermal cycling will abrade through to the conductor over time.
- Pack of 25: The 25-piece pack quantity aligns with typical panel or raceway installation runs — enough to complete a mid-sized job without over-ordering. At a consistent package quantity, BOM-based procurement is straightforward.
Integration & Compatibility
The CSB42-150-230-Q is designed for use with Panduit metal buckle straps (MS series), MLT cable ties, and cable clamp accessories in the corresponding width range. It is suited for use in hostile environments — the evidence cites applications where short-circuit protection and infrastructure reliability are the design requirement, not just cable tidiness.
The 70mm maximum bundle diameter sets a hard upper limit on where this sleeve can be used. For larger cable bundles, a wider or longer sleeve from the Panduit wire management line is required — do not try to force this sleeve around an oversized bundle, as it won't close properly and the clamp will bear directly on the bundle edge.
This sleeve pairs directly with wire routing and cable management hardware including cable trays, conduit clamps, and panel tie-down systems. For full cable tie and strap selection — including the metal straps and MLT ties this sleeve is designed to cushion — review cable ties and straps in the same family.

Frequently Asked Questions
Q: What cable clamp types is the CSB42-150-230-Q compatible with?
A: The CSB42-150-230-Q is designed for use with Panduit metal buckle straps (MS series), MLT cable ties, and MS straps. It is not a universal sleeve — confirm your clamp model's bearing width matches the 42.7mm sleeve width before ordering.
Q: What is the maximum bundle diameter this sleeve will accommodate?
A: The maximum bundle diameter is 70mm. For bundles larger than 70mm, this sleeve will not close fully and a different size is required.
Q: What material is the CSB42-150-230-Q made from, and does it matter for my application?
A: The sleeve is made from TPU (thermoplastic polyurethane), which provides flexibility and durability under clamp load. The product is also described as suitable for hostile environments. If your application requires halogen-free or low-smoke (LSHF) material — common in enclosed transit or building infrastructure — verify the specific material compliance for your region's requirements before specifying.
Q: How many sleeves come in one package?
A: Each package contains 25 individual pre-cut cushion sleeves.
Q: What is the overall length of the CSB42-150-230-Q sleeve?
A: The sleeve measures 274mm (10.8 inches) in overall length and 42.7mm (1.68 inches) in width, with a profile height of 2.5mm (0.1 inches).
Q: Can this sleeve be used in outdoor or harsh industrial environments?
A: The CSB42-150-230-Q is described as suitable for use in hostile applications and environments, and is intended for short-circuit protection applications where cable infrastructure reliability is a design requirement. Confirm specific environmental ratings with Panduit for your deployment conditions.
The detail that stands out to me on the CSB42-150-230-Q is the 2.5mm profile height — that's thin enough to retrofit into existing clamp assemblies on live panels without replanning cable tray clearances, which matters when you're adding short-circuit protection to an already-commissioned run rather than designing from scratch.
Technical Highlights:
- 70mm Max Bundle Diameter: Covers the majority of medium-density power distribution bundles — enough for a 25–30 conductor run depending on wire gauge. Size up if you're managing large feeder bundles.
- TPU Flex-and-Return: Unlike rigid sleeves that crack on re-entry, TPU recovers after clamp load is released — important on any installation that gets opened for maintenance on a recurring basis.
- Pre-Cut 274mm Length: Field-consistent sleeve length across all 25 pieces means assembly quality doesn't depend on who's cutting stock sleeve that day. Relevant on multi-tech panel builds.
Deployment Considerations:
- Match the sleeve width (42.7mm) to your specific Panduit MS or MLT clamp model before ordering — the sleeve must cover the full clamp bearing surface to provide the intended short-circuit protection.
- The 70mm maximum bundle diameter is a hard stop. Attempting to use this sleeve on an oversized bundle will prevent proper closure and leave the clamp in direct contact with the cable jacket — the exact failure mode this sleeve is meant to prevent.
This sleeve is the right specification for industrial panel builders and electrical infrastructure contractors running metal cable clamps in hostile or high-reliability environments where a single insulation breach event is unacceptable — power distribution in manufacturing, data center PDU runs, and transit electrical enclosures are the scenarios where this part earns its place in the BOM.
