MK Electrical Dado Trunking with 63A busbars is made up of a white rigid unplasticized polyvinyl chloride (PVCu) housing body. The Powerlink Plus is a busbar trunking system developed to meet the power and data distribution needs of offices, schools and laboratories. The system offers flexibility for future adaptations. The pre-drilled trunking bases eliminates the need to measure and drill fixing holes on site.
