Hydraulic Ram Release Knob

thingiverse

So, I tackle numerous projects in my garage that demand the use of hydraulic rams, jacks, and engine hoists. Time after time, I find myself wasting too much time searching for the stupid jack/ram handle to release the pressure. To simplify my life, I came up with these knobs to install over the release valves and minimize the amount of time I spend looking for those elusive handles. There are two knob designs available for two different style releases: a round design (approximately 0.360 inches in diameter with a 0.155 inch T-rod) and a notch design (approximately 0.375 x 0.270 inches with a 0.155 inch T-rod). The notch design has been confirmed to fit the Harbor Freight Long Ram Hydraulic Jack P/N 56215, while the round design is confirmed to fit the Harbor Freight 2-ton Folding Engine Hoist P/N 69514. It's likely that this round design will work with most pressure release valves with measurements similar to those listed above.
