WHEN YOU NEED CLEATS THAT WITHSTAND MODERATE LEVELS OF SHORT-CIRCUIT
Heavy Duty Polymeric & Stainless Steel Cable Cleat, for cables in trefoil formation. The Ellis Our Colossus cleats are a direct alternative to the all polymer (polyamide) cleats offered by some manufacturers. The unique design of Colossus combines a Low Smoke and Fume Zero Halogen polymer frame with the strength of a 316L stainless steel skeleton.
The strength of polymer cleats is typically quoted in Newtons and depending on the variant, range from 10,000N – 30,000N. On the same basis, all Colossus cleats have a strength of 63,000N irrespective of variant.
The composite structure of Colossus allows a compact design, which in turn allows for closer cable runs, in comparison to its all polymer competitors. The stainless steel element of Colossus ensures that the effects of UV radiation and “creep” (exhibited by all thermoplastic polymers) can be ignored. Colossus cleats will also retain cables (whatever the mounting orientation) in the event of a fire.
With its depth increasing across the range, Colossus is ideally suited for cleating very large diameter cables in trefoil (up to 170mm). The saddled version of Colossus is ideal for cleating cables simply supported at large centres, typically from 3 to 8 metres.

Matters of corrosion. One of the most important issues to consider when specifying cable cleats is the risk of material corrosion – not just as a result of the installation environment, but also from other metals which the cleat is in contact with.
Galvanic corrosion. Galvanic corrosion occurs when dissimilar metals are placed in contact with each other in the presence of an electrolyte.
Stainless Steel: In general, cable cleats are manufactured from austenitic stainless steel due to its non-magnetic and corrosion resistant properties – the former ensuring the cleat won’t induce eddy currents or localised heating of the cable.
Coatings: The corrosion resistance properties of stainless steel are a result of chromium, which reacts with oxygen and forms a self-healing impervious layer of chromium oxide on the surface of the steel.
Fixings: Closure fixings on cable cleats are fundamental to the loop strength of the cleat and its short-circuit withstand capability.
Galvanized Steel: Contracts often require a guarantee regarding the life expectancy of a cleat. If the installation is designed correctly and all other corrosion issues have been considered this is a relatively simple exercise for stainless steel products. With galvanized steel, life expectancy is determined by the thickness of the zinc coating.
Operating Temperatures: Our standard ranges of cleats are designed for use in ambient temperatures ranging from -50°C to +60°C and with cable conductor temperatures up to 90°C
