The Walkway from Foul Fingers is a really interesting obstacle as you get 2 platforms, and 3 rails. The middle rail is detachable, so there are a couple ways you can set this spot up! Foul Fingers hand crafts quality cement fingerboard obstacles in Colorado. Realism is an important part of any fingerboard set up, and nothing is more real than cement obstacles like the ones you would be hitting in the streets!
