QR code

March 2014 - We are now transitioning to QR codes on our products and packing lists. When scanned on a smartphone or tablet the QR code will display a drawing of the part if it is a stock part, or on job specfic parts it will display layout and detail drawings. One can view installation drawings on a tablet right in the field! Look for these to appear on weather proof labels on our products and at the top of our packing lists.

We are excited to be able to provide this technology to our customers.

Jan 2014 - Trenwa will be exhibiting at the 2014 IEEE PES T&D Conference & Exposition in Chicago April 14-17. Please stop by and visit our booth (map).

We are excited to be able to provide this high quality, value added equipment with our trench solutions. This is the best way to manage, organize and protect cables inside our trenches by mounting them on the trench wall, off the floor and out of the way!
