DoorJak Door Lifter Cart, Hardwood Steel Doors
Hardnox LLC was started in 1997 when Jim Echternacht, a general contractor in Santa Barbara, California, found himself and his crews struggling with heavy and oversized doors they were asked to install. He knew there had to be a better way - thus the idea for the DoorJak was born. After months of engineering, testing and prototyping, the DoorJak 100 was ready for the market. All Doorjak products are in stock and are shipped from our factory in Ohio.
