Dolly Kit

The WINCO Industrial Series, 4-wheel dolly kit will give your generator excellent mobility on the ground. With the 10″ flat free tires you can get through mud, snow, sand and soggy lawns. The solid steel axle runs the entire width of the generator therefore it provides superior strength. Our durable baked on powder coat paint system protects the parts from corrosion.

Generator Cover

Storage can be hard on your generator. Moisture and dirt can damage the engine and generator windings over time. Often during transport and storage the generator is damaged by scrapes and dents. WINCO’s heavy tailored canvas cover will protect your generator from these hazards protecting your investment. A built in band keeps the cover in place.

Plug-In Line Voltage Monitor

Plug-in Line Voltage Monitor is a compact voltmeter that can be plugged into the 120-volt receptacle on any WINCO generator to assure you that your generator is functioning properly.


These plugs are perfecting for running power into a transfer switch or other distribution box. The cord is sourced locally and specifications should be determined by a competent electrician taking distance, load, and other environmental factors into account.
