Let me be very clear. Garage parking accidents are not gender specific. I've never come across my wife's compressors, generators, or tool boxes. It can happen to anyone. Anyone who has ever driven a military or construction vehicle knows the critical importance of wheel chocks. Driving into a garage is an art few have mastered, especially on a pickup truck where the rear bumper extends 4 feet past the rear end. Tires. Pushing up a wall or garage door is more forgiving with a Camry than with a 2-ton tractor. I've used these chocks anywhere I park anything other than an ATV for years and have avoided significant property damage in many cases. .It's the luxury of slowly pulling into a parking lot without worrying about bumping into something that hates being hit. These pads are professional quality and will outlast most users. I've seen them on trucks and lane clearers. Eyebolt with attached rope makes it easy to remove. However, I don't use them that way. When determining the best location for a particular vehicle, I fasten the chocks in place. A car tire won't move them much, but if I bump into them they tend to move a little. If the surface is concrete, a small amount of liquid nails or construction glue will hold it in place well. . WARNING! Don't use too much. Back in the early 80's I glued a block of steel to a concrete floor with liquid nails. If I had to move it, I had to pry it out with a crowbar. It broke off along with a good chunk of concrete floor. If I'm using these blocks in a dirt floored shed, a couple of 12" spikes behind them will work. Spikes cost about 99 cents at most hardware stores. Buy them to experience and avoid costly repairs.
