Sta-Rat Semi Tandem Axle Stopper

I have been using this for nearly 6 months. And I am STILL Using it Every Work Day.I found, that the speed limit to bumping it, is approximately half Idle reverse (especially fully loaded).I hang it to the inside of the slider rail, and primarily use the bigger (weaker) end.Learning the speed, I did odd shape the cup, but, it's still in use. And I slide it in from the outside....I did have it twist apart last week, while sliding it somehow moved and caught between the rail and tandem frame, but the mechanics at the main shop were able to weld it back together in minutes.For those of us, not paid on the clock, but have loads that have to be spaced at a specific spot, this is a Major time saver, I place it while checking tires/lights/releasing air pins, slide the axles and lock them (air pins), and retrieve the stopper while checking all the pins are locked, before hitting the road. No more back and forth, in and out, trying to hit the Exact hole this load requires for balance, just place it, slide it, retrieve it, in, out, gone....If your on the pay to clock, whatever, but, most of us are on pay to run, so, no moving, no money, get it done, and get it gone, make our $perhr higher....So, if your paid by the Load or the Mile, or, your just tired of getting in and out trying to hit your spacing, this is going to help you big time, just, remember, no more that half idle reverse speed, when you hit the stop....

It's very complicating to use. It doesn't sit in the holes very well.

Broke after 2nd use

This product was a challenge to operate. The large part was to big and the small part too small so it never held its position. Then it snapped like a twig after a few uses.

This product let's you put the pin in the right hole the 1st time .

It solves the purpose

Worked for me. I'm satisfied

Great has 2 different sizes ,very convenient
