This product did a good job to level out the rain gutter at the end of my driveway. It’s a much more comfortable ride over the curb now with my car and motorcycle. I bolted them down to the curb so they don’t move around. Took about 20 minutes. It comes with the bolts to secure them together and to the curb but you need a drill though for the initial holes in the curb. Other than that, just hammer it down and tighten it with a wrench. Overall good product and pleased with the purchase.
