Developed by a practicing physical therapist in 1985, the Stretch Ranger was the first web-strap over-the-door pulley on the market. Today it is still the market leader in design. A low cost, simple-to-use device, the Shoulder Pulley helps increase and maintain range of motion in all planes of shoulder motion.
Used in the home, it allows patients to increase the gains made in the clinic and helps speed the recovery process.
