This product is a nice addition to my HF 20 Ton shop press. It is well constructed, fit and finish is good. When installed, this knob makes it very easy to open and close the release valve without tools

Works with the 12-Tom bottle jack just fine. Put this on around the pin, turn as far as possible, then insert and tighten the set screw with the Allen wrench.
