I have a 19-foot travel trailer with an Ultra-Fab 3002 electric A-frame jack. To protect the electric motor, I use a thoroughly cleaned 182- ounce Clorox plastic jug. I measured about 11 inches from the bottom of the jug and cut the handle and cap portion off. I then slit from the bottom about 1 inch to the top and slipped it over the motor. It works great!
