Rakes Deluxe Forearm Cuff consists of two components: a tapered forearm cuff and a metal stand. During a polygraph examination the metal stand is placed upon the arm of the polygraph chair and the subject's forearm (with the cuff on) rests upon it. The design allows for the elimination or reduction of pressure applied on the cuff by the arm's weight, and reduces the restriction of blood flow. The Rakes Cuff helps to ensure the utmost accuracy of the polygraph examination. It is more comfortable and stable than the Kovacic Arm Cuff. Compatible with LX4000/LX5000 computerized polygraph and our conventional polygraph instruments.
