Simple easy to use security device for a semi truck.I don't know how well it works or how easy thieves can break thru thisHowever some sort of deterent is better then nothingWhy would someone who wants to steel go thru the trouble when most trucks don't have any security device at all.

It fits a bit lose. Not sure it will withstand a thief with a good crow bar. But its shinny and it looks good on there. Well made and closed up nicely. Some adjustments may work but not quite well.

Works great. Precision made. Beat my expectations by far. Definitely recommend this for added security. Especially if you want to leave your ac on during hot days or heater on cold days. Well worth the price.

Works as intended. Does not fit aftermarket knobs I have but may fit some styles. I used a Dremel tool and cut some material away on the inside to accommodate the knobs I have.Finish is terrible on this lock. Very rough
