Safe Jack Flat Jack pads have 16X the surface area of the jack ram alone. That means that instead of 4900 lbs. per square inch (6000 lb. load) the pressure on the load would only be 375 lbs. That's a lot safer. In addition, the size of the pad makes the jack far less likely to slip or tip. Jack pads simply slip on the end of the jack ram or extension without tools. Flat Pad is 4X4 inches.
Fits most 6 Ton bottle jacks (typically 1.25" diameter ram).
