5.0 Pretty Sure Someone Already Tried It

This little baby is a must have if you are mounting your farm-style jack outside your vehicle. Very heavy in the hand, it is definitely got some quality construction going on. Feels like it weights 2-3 times the standard non-locking knob that came with my HM-900 mount. I am also pretty sure someone has already tried it, as I left my vehicle being able to read the Hi-Lift logo through the windshield, came back and it was turned 180 degrees. Keep unsavory people from taking your hard earned tools, spend the $30 on it. I believe it mounts on a standard 3/8" UNC bolt, opening up a wide variety of locking options.

5.0 Hi Lift lock - not for bull bar

I bought this for the bull bar mount and it is the wrong thread size. Apparently this is meant to fit the hood mount. I should have checked the size first. The quality is great and I will keep it for another use.

4.0 Caution. Do not over- tighten.

Good product. Do not over tighten as the handle will strip out and removal will be difficult.

5.0 Great product

Love the added protection. Works as expected when it's locked it spins freely.
