This is the cover that is identical to most of the dashboards for the Tesla Nappa Black grain finish.  We carry this in the older EZ-Pass, pre 2012 square style transponder as well as the newer I-Pass, post 2012 round shaped transponder.  Please see below for pictures of the two different types of transponders as we have seen the newer I-Pass also called the EZ-Pass in some states. 

These cases are for the following states: DE, IL, IN, KY, ME, MD, MA, NH, NJ, NY, NC, OH, PA, RI, VA, WV.

Our cases attach to the EZ-Pass and I-Pass using two straps and the hook and loop Velcro system.  As you can see from the second picture, the straps do not interfere with the transponders other Velcro strips that allow the transponder to attach to the windshield.  They are designed not to interfere with the signal to the reader above the toll road.  They also resist fading in direct sunlight.
