Alpha Aluminium Trefoil Cable Cleats

The standard Alpha cable cleat is manufactured from extruded aluminium strip (6000 series), suitable for installing single-core power cables in trefoil formation. The Alpha cleat is designed for use within industrial and commercial installations where light to moderate levels of short-circuit withstand are required.

The unique design of the trefoil ALP range allows for rapid installation, while continuing to provide a strong, robust and lightweight cleat, leading to it becoming a preferred option with many installers.
  • Maximum Short Circuit Test: 72kA peak @600mm centres (96kA peak @300mm centres)
  • Grip ridges on the inside of the cleat to eliminate cable slippage.
  • Strong and robust design, resists brittleness and failures.
  • No hidden defects from casting processes.
  • Aluminium construction, no hinge pins to corrode.

The aluminium Alpha cleat conforms to a number of standards. It meets the International Standard IEC 61914:2009, is short-circuit withstand tested to 31.4kA RMS (72.4kA peak) and the full range is also compliant with the London Underground Engineering Standard 1-085 and approved for use within the LUL network, Product Approval Register No: 360.

A version is also available with a LSF nylon base pad, insulating the cleat from the surrounding support structure, dramatically limiting the effects of possible electrolytic action between the dissimilar metals.

The cable cleat is easily fixed to cable ladder rungs or 41mm wide steel channel with the use of a Trefoil cleat fixing kit. Featured in each kit: M10 BZP hexagon set screw, M10 flat washer and M10 plain channel nut.
