The new Rancho/Jaeco mount has been designed to address the requests of the therapist and care providers for a system that was easier to set up and more adaptable to the variety of wheeled mobility systems in use today. This was accomplished with the use of an open jaw" clamp that can accommodate tubing as small as " and as large as 1", even over fabric covers. (Some seating systems will require an adaptor or relocator for optimum positioning of the mount. The unique scroll wheels for anterior/posterior and medial/lateral allow quick and simple balancing without tools. The mount is universal left and right. This mount can be used with all of the current mobile arm supports. Rancho/Jaeco mount must be purchased separately.
