McKesson's wrist splint with single one-pull design is used as support for carpal tunnel syndrome or to aid in the immobilization of the wrist following mild sprains or strains. The nylon material is perforated for breathability and comfort. A soft inner liner allows smooth donning and comfort. The one-pull design conveniently fastens dual elastic straps using D-rings, and a single contact closure. The dorsal stay can be moved proximally or distally within its adjustable stay pod so user can control range of motion. A secondary dorsal stay may be removed to accommodate rehabilitation needs. The included palmar stay is contoured and may be adjusted for specific user needs.
