I have a Bergantino factory padded cover that fits the NV series cabinets. It is as brand new. Bought it when I bought my NV610 and never use it. I just walk around it all the time so maybe someone needs one.
The cover has cutouts for the top grab handle, side spring loaded handles, and cutouts for the wheels. It is the Bergantino cover and not an aftermarket brand.
Can be seen on the Berg website.
Thanks!
