Industrial step ladders with the added benefit of non-conductivity for safe working at height in electrical environments. Constructed in a “builder’s style” these high quality steps are tested to EN131 150Kg and electrically insulated with 1 – 30,000 volt bleed ratio. Heavy duty fibreglass stiles with large serrated steps and rubber feet provide insulated non-slip working in the most testing of environments, also strong metal supports and large plastic moulded tool tray make this a very versatile and cost effective step ladder for all industrial and trade conditions.
