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 steel with a black oxide finish and built to last. The inside diameter of the thumb knob that fits over the pressure release valve is 0.37"
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.
I bought two. One for my harbor freight hydraulic press and one for an older bottle jack I have. I had to make some minor modifications to the bottle jack but the end result on both were great.
The thumb knob for 20 ton bottle jack a very nice upgrade. A ton more convenient than the bar tool!! Super fast shipping too.
Installed on a HF 20 ton air/hydraulic jack. Superb finish on the machining. Fits perfect with zero slop. Well worth the money versus my time of fabricating something else. Highly recommend.
Good solid heavyweight knob, installed on HF air/hydraulic jack on 20 ton press/Swag finger brake .This is a great addition for anyone who doesn't like "breaking the pace" when fabricating.
Works perfect! Taps on nice and tight with a rubber mallet.
