Aluminum Claw Cleats
Engineered for single or multi-cable vertical risers and tight utility tunnel installations. Features a compact footprint, integrated claw grip mechanism, and high mechanical retention under severe vibration.
- Single-bolt rapid tightening design
- Optimized for vertical runs & cable trays
- Custom liner options (LSOH / EPDM)
High Tension Cable Clamps
Heavy-duty structural clamps engineered for high-voltage transmission (110kV / 220kV / 500kV) circuits. Built with thickened cross-sections to withstand extreme dynamic fault currents without mechanical deformation.
- Withstands short-circuit faults up to 150kA
- Dual-bolt heavy-duty clamping structure
- Zero eddy current heating in high-current runs
Aluminum Cable Cleats
Versatile single-core and trefoil formation cleats for industrial power distribution, renewable energy substations, and MEP electrical framing. Provides lightweight, corrosion-free, and reusable cable securing.
- Trefoil & Single cable arrangement options
- Direct compatibility with 41mm strut channels
- 1/3 weight of conventional carbon steel cleats
Why Specify Lonsonstrut Aluminum Cable Cleats?
Engineered to overcome the safety hazards and installation overhead associated with traditional fabricated steel and plastic cleats in demanding electrical installations.
Zero Eddy Currents
Non-ferromagnetic aluminum alloy eliminates magnetic hysteresis and inductive heating around single-core AC cables, preventing thermal degradation and line losses.
Short-Circuit Withstand
Cast and extruded from proprietary high-yield alloys. Retains cable geometry against immense electro-dynamic repulsion forces during severe power fault events.
Tunnel & Coastal Durability
Naturally forms an oxide barrier. Outperforms galvanized steel in humid utility tunnels, high-salinity coastal areas, and underground metro spaces without repainting.
Modular Strut Interface
Engineered to lock directly into standard 41×41 and 41×21 strut channels via channel nuts or custom mounting plates, accelerating site installation schedules.
