The crush-resistant design of Grote’s UltraLink Power Cords means they can survive being run over by a heavy-duty vehicle while conventional hollow core designs are permanently deformed and rendered useless.

Adhesive bonds cable to plug, eliminating need for supporting spring and preventing moisture from entering the back of the plug
UltraLink™ power cords exceed minimum legal lamp power delivery requirements for single or double trailer configurations
Advanced polymer jacketing material provides complete sealing and abrasion protection between -55°F and 190°F (Premium Versions)
Zinc die-cast plugs are filled with elastomeric material that resists crushing & acts as potting to seal solid brass terminals from moisture
Solid brass terminals are corrosion resistant, and provide superior current capacity with minimal voltage drop
Provides excellent recoil memory, chemical, and abrasion resistance
