from my Dad, never used.


Comfortland introduces the Comfortmax shoulder/arm abduction system; a lightweight, universally-sized alternative to traditional shoulder abductors. Featuring a unique, design, the CK-800 includes telescoping arms, eliminating the need to keep several sizes on hand. A durable, 2 removable wedges allows shoulder positioning at 0, 15, 30, 60, and 90 degrees, while the strapping system allows the CK-800 to be worn on the left or right arm with minimal adjustment.
