EzyStrut manufactures a range of cable ladder sizes conforming to load requirements. One of these is the Nema 1 Cable Ladder, conforming to Nema 12A loading requirements.

Nema, which stands for National Electrical Manufacturers Association is a US organisation who's standards for electrical equipment are recognised all over the world.

To meet the Nema 12A specification, a cable ladder has to support a rated load of 112kg per metre over a span of 3m. EzyStrut's Nema 1 Cable Ladder (sold in standard 3m lengths) meets this standard.
