Klein's 6 Ft. Glow Rod is made from strong, flexible 5/32 In. diameter Fiberglass and is perfect for pushing or pulling wire through existing walls, attics or across suspended ceilings. When charged, the luminescent rod remains visible while fishing in dark spaces and is rechargeable in any light source. The small 5/32 In. diameter allows for greater flexibility while extending into tight bends such as through outlet box holes. Each rod features a permanent "bull nose" attachment on either end and is rated at a maximum 200lb. pull strength for light to medium duty jobs. The 6 Ft. x 5/32 In. size is great for light commercial and residential applications.
