Klein's improved upon their 15' Glow Rod set by adding a very protective coating that prevents splinters. This kit is used to install wires above ceilings, through walls and under carpets and raised floors. Luminescent rods glow in the dark and are rechargeable in most available light sources. 3/16" diameter Glow Rods are extremely flexible to navigate tight bends and narrow openings. Connect individual sections end-to-end to create a variety of lengths. Threaded connectors are beveled on both ends to prevent snagging and hang ups on obstructions.
