INTRODUCING LOCK30 - Locking Power Extension Cord

The last extension cord you will ever need.

LOCK30 - What is it?

LOCK30 is an innovative lockable extension cord that was introduced into the Canadian market in late 2016.  This ingenious device made its debut at the Fall Home Show in September of that year. The product was selected by the show’s management as one of the favourites of Fall 2016 show and featured on Tina’s Fall Favourites. It was also demonstrated on a segment during CityTV’s Breakfast Television.

The concept of a lockable cord is not new. Currently, all commercially available locking cords utilize an external button or rotary switch. This is the design fault of these other products. Having an external mechanism makes the cord prone to accidental release due to cord movement or external force against the switch.  In the case of a rotary switch, they are easily broken, thus rendering the cord useless.

With its patented design, LOCK30 addresses the shortcoming of these existing products by eliminating the need for an external, raised switch.  With a simple push and twist motion, the plug is locked and unlocked with ease.

As for the name... It is a 30° turn to lock and unlock a plug.  Hence LOCK30.


Hold and insert fully.

Push and turn CLOCKWISE.
