5.0 Hi-lift jack mount locking knob

So far so good. I’ve only had it on for about 2 weeks now. I had to replace one that was the non-locking knob since someone stole it.

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.

5.0 Great product

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

4.0 Caution. Do not over- tighten.

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

Q: Will this work with the Warrior hood mount (1542)? I have this mount and I need to secure the jack without using some rope lock. Answer this question

A: Hi Jeepers Creepers, No, looking closer at the Warrior hood mount this Hi-Lift lock won't fit properly. Thank you for the inquiry.
