I have just received the curb ramps that I ordered. I searched the internet and the link brought up an article on the 10 best curb ramps out there. This was rated 1st place. It's lightweight and very durable. It also has two pre-drilled holes so you can bolt it to the floor if needed. I chose it because the price was very affordable and because it was lighter than the black rubber ones. We can put them in the garage when it rains so they don't block the water. Thumbs up! High quality hard plastic.
