- No metallic parts for safe installation
- Network Rail NR PADs approval
- Meets London Underground LUL 1085-1 material approval requirement
Ellis Patents No Bolts cable cleats are non-metallic polymer single cable cleats for cable diameters ranging from 18-55mm for industrial and rail cable applications.
Ellis Patents No Bolts cable cleats are part of the single cable cleat range and are fully polymeric cable cleats designed for fast installation – the cable cleats are easily “stackable” and requires no conventional fixings to supporting steel-work for use in underground rail tunnels. The Ellis Patents design also allows for additional No Bolts cleats to be stacked on top of one another with nothing more than a small turn of a unique fixing lock.
Due to its non-metallic high strength nylon design the Ellis Patents No Bolts cable cleats are impervious to ‘bi-metallic corrosion’ and suitable for use in the harshest of environments including underground rail tunnels – a range of fire-rated cable cleats are also available manufactured from stainless steel for use with fire resistant / fire performance (FR FP) cables.

International Standard IEC 61914:2009
Ellis Patent cable cleats with international specifications are used to clamp and retain LV MV HV cables including 11kV and 33kV networks depending on short-circuit calculations according to IEC61914 calculations.
For cable installations where corrosion protection is required, including onshore and offshore substations or hazardous area locations, see our complete range of ➡ stainless steel cable cleats.

Live Cables and Health & Safety Improvements
The initial problem encoutered by Network Rail was that live cables were having to be removed from cable cleats, work carried on around them, and then somehow placed back between tightly spaced upright studs at regular intervals along an entire cable run. Ellis Patents addressed the issue by designing a brand new cable cleat that could be stacked and fixed with nothing more complicated than a quarter turn fixing lock. This means additional cable runs can be added quickly and easily, without any need to tamper with existing cable installations. The rapid-fit nature of the Ellis No Bolts cleat is further enhanced by the replacement of fixing nuts with a push-fit locking mechanism that securely fastens the lower and top section of the clamp together. In addition to its PADS approval, the Ellis No Bolts cleat also meets the London Underground 1-085 approved material standard, and conforms with international cable cleat standard IEC 61914.
