The Standard Golf Company is a manufacturer of golf course furnishings and accessories. It is based in Cedar Falls, Iowa. Golfers usually see the Standard Golf logo and brand name on flagsticks, flags, cups, ball washers, tee markers, and other furniture on the golf course. The company also manufactures custom signage for courses. The "ad in the hole" system - a once-popular form of revenue for a course, consisted of a plastic impact-resistant bottom that fits Standard Golf's original plastic golf hole liner - marketed as the "Riji Cup".
