Engineering Excellence

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.

NON-FERROMAGNETIC ALLOY

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.

TESTED TO IEC 61914

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.

ZERO MAINTENANCE

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.

SEAMLESS CHANNEL INTEGRATION
