3-D Printed Thumb
Knob For Bottle Jacks With A "Flared" Open/Close
We save you the hassle
of using the 18" long handle to open and close the pressure release valve on many of your bottle jacks or long ram's. This 3-D printed knob
is designed for the flared or "smashed" pressure release
valves found on many bottle jacks.
The flared or
"smashed" ends on these bottle jacks vary significantly from part to
part, hence a machined knob does not make a good candidate as it will not
conform to the different profiles on the bottle jacks.
To install the 3-D printed knob you simply press the knob on the flared
*NOTE* : If your bottle
jack has a round stud with a cross pin, you will need our machined thumb knob
which can be found HERE.
