In 1985, our co-founder, Bill Bolinger, a practicing Physical Therapist, frustrated with the high cost and low quality of home exercise devices, decided to start making his own. His Home Ranger® Shoulder Pulley was so successful it has since become the best-selling home shoulder pulley on the market. This simple and effective device has set a standard in the industry. It is inexpensive, durable, easy to use and completely portable. Prior to its creation therapists had two options: they could either go down to their local hardware store, buy a pulley and some rope and make their own, or ask their patients to purchase one of the expensive clinical models. Spurred on by the success of the Home Ranger, Bill and co-founder Judy Ray began to create other products. In 1987 they formed PrePak Products. The company's growth over the years is a result of a steadfast commitment to customers and exceptional product quality. All products in PrePak's line are developed by therapists working in the field. You'll find practical, innovative products that help people recovering from shoulder, back, neck or knee injuries -- products that are useful not only for rehabilitation, but for general fitness as well. All of the home exercise devices come with illustrated, easy to understand instruction booklets.
