IDEAL Electrical E-Class Fiberglass Fish Tape, 100-Foot (31-046) vs Klein Tools Multi-Groove Fiberglass Fish Tape with Nylon Tip, 50-Foot (56382)
Which should you buy? Our verdict on both, pulled from our full The Best Fish Tapes: 4 Compared (and One to Skip) comparison.
The E-Class is the only tape in this comparison where the maker prints a voltage figure and puts a non-metal eyelet on the end, and IDEAL publishes the strength, the case size and the repair procedure alongside it. Klein's multi-groove fiberglass gives you the same non-conductive tip and a replaceable one at that, in a shorter, cheaper package, at the cost of any published strength number.

IDEAL Electrical E-Class Fiberglass Fish Tape, 100-Foot (31-046)
Buy itThe only tape here whose maker puts a voltage number on the tape and a molded plastic eyelet on the end.
- IDEAL states the fiberglass core is non-conductive up to 1000 V, the only voltage figure any maker in this group publishes.
- The end is a molded glow-in-the-dark plastic eyelet, so the first part into the box is not metal.
- Published as 3/16 inch tape, 350 lb pulling strength, 100 feet in a 12 inch case, with a documented eyelet repair kit (31-044).
- IDEAL footnotes the 1000 V claim as based on internal testing, so it is the maker's own number and not a third party certification.
- IDEAL's own user guide still warns not to use the tape on or near live circuits or energized equipment.
- 350 lb is the middle of IDEAL's non-conductive line, below the 500 lb S-Class.

Klein Tools Multi-Groove Fiberglass Fish Tape with Nylon Tip, 50-Foot (56382)
Buy itThe short, cheap way to get a non-conductive tape with a non-conductive tip, if you can live with fifty feet.
- Klein lists the tape end as a non-conductive nylon eyelet, narrower for feeding and chamfered so it catches less on the pull back.
- The grooved profile puts less surface against the conduit wall, which is the whole argument for buying this shape over a plain rod.
- Light and compact at 2.7 lb in a 13 inch polypropylene case, and the tip is replaceable with Klein's 56025 repair kit.
- Klein publishes no pulling strength or tensile figure for this model, so you cannot compare it on paper with the IDEAL or Greenlee numbers.
- Fifty feet runs out fast on commercial conduit or a long attic run.
- No published voltage or dielectric rating, only the word non-conductive.
