We save you the hassle of using the 18" long handle to open and close the pressure release valve on any of your bottle jacks or long rams. It is fully machined out of aluminum and built to last. The inside diameter of the thumb knob that fits over the pressure release valve is 0.37"

This version of our Thumb Knob is designed to work with pressure release valves that use a roll pin. To install you simply press out the roll pin on the ram, slide over the SWAG machined thumb knob then reinstall the roll pin.

Note: If your bottle jack release valve has a flared or "smashed" end, or a cast cross pin, you will need our 3-D printed thumb knob which can be found HERE.
