Traditional Pegboard Extenders mount to one level of pegboard, allowing another level to be attached farther forward. The result is a configuration able to display long-handled items to the rear, and gain extra vertical display space up front. This is a great merchandising concept that I do not see often enough. And though this Traditional Pegboard Extenders example is not the best execution I have ever seen, it should convey the concept. I will search for better examples to share with you.
