Panduit CBH15L50-V6 Trefoil Cable Cleat Mounting Bracket

The Panduit CBH15L50-V6 mounting bracket provides drill-free attachment for trefoil cable cleats on ladder rung systems in high fault current environments. Built from Type 316L stainless steel for corrosion resistance in harsh industrial and marine installations, this 15mm×50mm bracket eliminates the need to penetrate ladder infrastructure while maintaining mechanical strength under short-circuit conditions. Compatible with Panduit's CCSSTR stainless steel and CCALTR aluminum trefoil cleat series, the bracket uses a hinged bolt assembly for fast, reversible installation without permanent modification to cable tray systems.

The CBH15L50-V6 is manufactured from austenitic Type 316L stainless steel, the marine-grade alloy specified for chloride-rich and high-humidity environments where standard 304 stainless would pit or corrode. The "L" designation indicates low carbon content (≤0.03%), which prevents carbide precipitation during welding and maintains corrosion resistance at weld seams—critical for brackets that may be field-modified or installed near welded cable tray joints. The 15mm standoff height positions the cleat body clear of the ladder rung surface, allowing full 360° cable bundle access for inspection and thermal management, while the 50mm mounting length distributes clamping force across a wide footprint to prevent local deformation of aluminum or fiberglass ladder rails.

The hinged bolt design uses a captive fastener that rotates into position beneath the ladder rung, eliminating the drop risk and alignment difficulty of traditional through-bolt systems. Installation requires no drilling, tapping, or rung modification—critical in retrofit projects where penetrating existing infrastructure would invalidate structural certifications or create ignition paths in hazardous locations. The bracket seats against the rung underside with a large bearing surface to resist pullout under fault current magnetic forces, which can exceed 50 kN/m on high-ampacity three-phase runs during ground faults.

Trefoil cable cleat systems are specified in power generation, petrochemical, marine, and datacenter applications where IEC 61914 short-circuit withstand testing is contractually required. The CBH15L50-V6 bracket is sized for Panduit's 15mm-class CCSSTR stainless and CCALTR aluminum trefoil cleats, which accommodate cable bundle diameters from 40mm to 150mm depending on cleat model. Typical deployments include offshore platforms and shipboard installations where 316L stainless resists salt spray and survives -40°C to +80°C temperature cycling, wastewater treatment and chemical processing facilities where the material is compatible with sulfuric acid and sodium hypochlorite, datacenter and telecom battery rooms where drill-free installation preserves fire ratings, and seismic zones where the hinged bolt design allows slight pivoting during lateral movement. The bracket is compatible with fiberglass, aluminum, stainless, and galvanized steel ladder systems without galvanic corrosion concerns.

The 5-piece packaging aligns with typical cleat spacing requirements: IEC 61914 specifies maximum cleat intervals of 600mm for single-core cables and 300mm for multicore bundles under fault conditions, so a single pack covers 1.5–3 meters of three-phase trefoil run depending on cable type and fault level. The natural finish eliminates the need for post-installation coating and maintains traceability for material certifications required on ASME B31.1 and NFPA 70 projects.
