“To our customers, vendors and partners around the globe; we are with you during this unprecedented time. Like it is for you, our side of the world is scary at the moment. The health risks are very real as is the economic fallout of this pandemic. We are working with our government as new help rolls out to deal with this. It’s obviously a very fluid situation and new things change daily, but at Torq/Lite® we are continuing to work. Both of our main offices are open & running, following the recommended guidelines and practices as issued by the CDC. Unless the government orders us to shut down, we will be ready to fill all orders received. We wish all of you well. We are here and ready should you need us.” Josh Francis, VP - Sales, Marketing & Business Development , Torq/Lite® Contact Us
