Product structure & benefit structure
TRI-series design & ease of installation
The TRI clamps consist of two parts: a base and a top, each with integrated chambers for mounting nuts. Both parts have two mounting holes for threaded rod or bolt attachment, plus an additional middle mounting option via a central hole in the base—ideal for added stability.
TRI vs. TRI ECO – differences and options
Both series are designed for trefoil configurations, but differ in weight and price. The TRI ECO series is lighter and therefore more affordable, while the standard TRI series offers maximum stability and durability.
Material, weather resistance and durability
The clamps are made of black, glass fibre reinforced polyamide (PA66), with exceptional physical properties:
- Halogen-free, self-extinguishing (UL 94 V0), non-magnetic, non-conductive, without sharp edges
- Resistant to oil, grease, frost, UV, ozone, salt water, acids and other aggressive chemicals
- Temperature range: continuous –80 °C to +120 °C, short-term up to +220 °C
- Comes with a lifetime warranty
Certification & reliability
The TRI series is NENENIEC 61914 certified and complies with additional standards and quality controls from agencies such as KEMA, SGS, KU Leuven, and UL.
Suitable for a wide range of applications
The TRI clamps are ideal for industries where reliability and electromagnetic balance are essential, such as:
Energy and distribution installations
Maritime and offshore projects
Infrastructure (bridges, tunnels, masts)
Industrial installations with high short-circuit currents
