Even more power to the people

How we went on to improve Mainline’s innovative sliding power track

The global leader in power track


We had worked closely with Mainline to re-engineer their innovative sliding power track to ensure it met the UK’s stringent compliance standards.

The track enables domestic and commercial users to reposition plugs and data points without the need for rewiring or new sockets.

As the product was launched with great success throughout the UK, Mainline returned to us to ask us to propose a more elegant solution for the terminal block that connects the power to the track.


The terminal block that was being used was a legacy from a previous design and as a result was not perfectly suited for purpose.

Of the two concepts that we proposed, one quickly emerged as the favoured option. It used plastic injection moulded parts encased in an over-moulded terminal that looked stylish, was simple to fit, held the cable more securely and was significantly simpler and cheaper to manufacture than the part it replaced.


Mainline has gone on to mainline win numerous awards globally for its innovative sliding power track,
including the RedDot Design Award and the Australian Design Award.
