These are 2 parking wheel stops, like a store parking lot uses (occasionally) only these are thick rubber instead of concrete. They work great for helping stop your car in your garage at the right place. I got them so my 90+ year old father could stop his car (why was he still driving?!) without bashing through my carport fence. They are better than a tennis ball on a string! Heavy rubber stay in place pretty effectively without staking them. Text 801-310-7109 no calls. Cash only $30 each That’s cheaper than KSL AI says to sell for!
