Genubi Industry Genubi Industry Rubber Curb, Black Heavy Duty Parking Blocks with Yellow Refective Stripes, Wheel Stop Stoppers for Car, Truck, RV, Trailer, and Garage, 2 Pack Professional Grade

They are pretty heavy. The weren’t the cheapest ones but i wanted a heavier weight block , so they wouldn’t slide as easy. They definitely do their job!

This product works as advertised. Bolted them to my garage floor for extra security, I doubt they would move even if I Hadn’t, but this way they definitely wouldn’t move. If you want to bolt them use a 3/8 drill bit. I would absolutely recommend this for anyone how needs it again absolutely fantastic.

These are very sold and appear to be good quality for the price

Really heavy-duty, stay in place on any kind of surface (even ice), no-brainer to use, handle is super helpful for getting them back out and away from the tire. Suggest ordering them at least a month before you need to use them. They really smell (rubber) when they first arrive for about that long, even when left outdoors a lot. They come in a white bag that reduces the smell to minimal, but that's a little inconvenient when using them a lot on a road trip. However, well worth that initial inconvenience for the safety and piece of mind they afford.

These are super! I've done the ball hanging from the ceiling which can be imprecise. I've done the motion-activated stop sign sticking up from the floor, which I found both awkward and annoying. This is the best solution I've encountered. Comes with bolts to drill into your garage flood but I didn't use them. These blocks are heavy and stay in place. Almost a year and they haven't crept up from where I originally placed them. When the car is out and you're working in the garage, you do have these blocks to step around but that is a residual problem with the stop sign and the tennis ball as well. Not as cheap as some other solutions but this is by far the best answer for home parking.
