Panduit CCAL1H4651-X One-Hole Aluminum Cable Cleat
The Panduit CCAL1H4651-X is a one-hole aluminum cable cleat engineered for securing single power cables in installations where short-circuit fault protection is critical. Certified to IEC 61914:2015 and tested to withstand peak fault currents up to 93.4kA, this cleat retains cables during electrical faults that would otherwise cause catastrophic whipping and infrastructure damage. Designed for cable diameters from 46-51mm (1.81-2.01 inches), it mounts directly to cable tray rungs via a single M10 bolt (user-supplied), making it ideal for datacenter power distribution, industrial switchgear installations, and utility substations where aluminum's corrosion resistance and lower weight offer installation advantages over steel alternatives.

Short-circuit faults in power installations generate massive electromagnetic forces that can cause unsecured cables to whip violently, damaging adjacent infrastructure and creating arc flash hazards. The CCAL1H4651-X addresses this by clamping the cable within a rigid aluminum saddle that's bolted directly to the cable tray structure. The one-hole clamp design uses a single M10 fixing point, allowing faster installation than two-hole cleats while maintaining full IEC 61914:2015 compliance. Testing to 93.4kA peak fault current means this cleat will retain the cable even under the extreme forces generated during a major electrical fault—the kind of event that can bend unprotected cable tray and destroy equipment. The 46-51mm cable diameter range covers common medium-voltage power cables used in 480V three-phase and 600V industrial distribution, including insulated conductors in the 1/0 AWG to 4/0 AWG range depending on insulation thickness.
Aluminum cleats like the CCAL1H4651-X are preferred in datacenter PDU runs, solar farm inverter feeders, and industrial MCC (motor control center) installations where corrosion is not aggressive and weight reduction matters. Aluminum's 2.7 g/cm³ density (versus 7.85 g/cm³ for steel) reduces dead load on long tray spans, and the natural oxide layer provides adequate corrosion resistance in controlled indoor environments. The one-hole mounting pattern simplifies installation on ladder-style cable tray where rung spacing is fixed—installers align the cleat to a single rung hole, insert the M10 bolt, and torque to manufacturer specification. When securing cables over dissimilar metals (aluminum tray with copper conductors, for example), install the optional insulating spacers and washers to prevent galvanic corrosion at the contact points. For multi-cable runs, cleats should be spaced per IEC 61914 Tables 1-3 based on expected fault current magnitude and cable stiffness—typically every 0.5-1.0 meters for horizontal runs and every 1.0-1.5 meters for vertical risers.
The CCAL1H4651-X is a vetted solution for installations where electrical inspectors verify IEC 61914 compliance and where integrators need documented fault current ratings for insurance and liability purposes. Competitors like Ellis Patents, Gewiss, and Niedax offer functionally similar aluminum cleats, but Panduit's cULus recognition and broad distribution through electrical wholesalers make this the go-to choice for North American projects requiring traceable certification. Pair with Panduit's insulating spacer kits (sold separately) when securing cables in mixed-metal tray systems, and verify your installation's fault current rating with your electrical engineer before specifying cleat spacing and fixing torque.
