These heavy PRO LOCK CUSTOM PRINTED EXTENSION CORDS are your best bet against thievery. Each of these Pro Lock Extension Cords are molded with a unique and patented Pro Lock female connector. What’s more, when a standard extension cord with a 15A-125V, 3 conductor male plug is inserted into our Pro Lock connector, it won’t pull apart. This also prevents accidental disconnects that result in an inconvenient loss of power. Simply pull down on the connector collar to disconnect extension cords.

However, the best part is that you can have these PRO LOCK CUSTOM PRINTED EXTENSION CORDS custom printed however you want, every 12 inches. Besides being a great feature in and of itself, it’s Absolutely Free! We’ll print your company name and phone number or website address every 12 inches down the entire length of the cord. Lastly, printed cords discourage jobsite theft and provide instant advertising and company recognition which will promote more business.


Specific product info:

Now let’s get to the details of these PRO LOCK CUSTOM PRINTED EXTENSION CORDS. First, these cords are manufactured to 12/3 AWG (American Wire Gauge) specifications. Second, each of the three conductors contain 65 strands of 30 AWG 100% copper wire. In addition to that, all of the copper is soft drawn & annealed for maximum flexibility under a full load. Third, our Pro Glo® high visibility cold-weather PVC insulation and jacket guarantees full working flexibility in temperatures as low as -58°F. Subsequently, these cords will never be too stiff to use!

These cords also feature molded on Pro Lock™ connectors that will not pull away from the cord body as well as offering extra water resistance. Moreover, they have an automatic locking feature. First, insert the male end into our Pro Lock™ connector. Second, push together to lock. Third, pull the collar down to unlock.

Century uses a high impact polycarbonate on both the housing as well as the collar on the Pro Lock™ connectors. This guarantees hard service and extra-heavy duty use. Besides that, these PRO LOCK CUSTOM PRINTED EXTENSION CORDS have a Pull Strength of 80 Lbs. horizontally or vertically. Equally important, they have a lighted Amber Power Check plug that indicates there is power running through the cord. The Pro Loc green lighted CGM connector identifies ground continuity in the circuit also. Our Pro Lock cords are available in Orange, Blue and Green. Lastly, they are UL Listed and OSHA certified as well as being cUL Approved for Canada.
