Why does a fish tape need to glow in the dark?
Glow-in-dark fish tape is designed to confirm tape position inside dark conduit or wall cavities without removing outlet covers or drilling inspection holes. By glowing, the tape is visible through seams in the conduit or at the far end — useful for plumbers and low-voltage installers working in enclosed walls and ceilings.
What situations call for only 20 feet of fish tape?
Short wall drops, single-room low-voltage runs, shallow attic cavity passes, and outlet-to-outlet cable fishing where the full run is under 20 feet. The 50550 is a supplemental short-reach tape, not a primary tape for conduit-based electrical work.
What material is the 50550, and is it conductive?
Fiberglass with a glow leader — fully non-conductive. The 50550 is safe for use in wall cavities and conduit where energized conductors may be present.
How is the glow activated?
Expose the tape to light for a few minutes — fluorescent or direct lighting charges the photoluminescent material. The tape then glows in low-light or dark conditions during use. Intensity fades over time and recharges with re-exposure to light.
What is the warranty?
Lifetime warranty from Klein Tools.
