Description
Greenlee FTS438W-100 Fish Tape 100' x 1/4"
Power through long, heavy-duty commercial conduit runs without tape buckling or bending. The Greenlee® MagnumPRO™ FTS438W-100 100-Foot x 1/4-Inch Steel Fish Tape is engineered for electricians tackling demanding, high-resistance wire and cable installations.
Featuring an extra-wide 1/4-inch oil-tempered spring steel blade, this tape provides significantly higher column strength than standard 1/8-inch tapes, allowing you to push long distances through larger conduit and past multiple bends without curling or kinking. The rugged, drop-resistant winder case includes an oversized ergonomic handle for reduced fatigue, high-speed pay-out and rewind, and an integrated viewing port that lets you gauge remaining tape footage while easily shaking out jobsite dust and grit.
- Extra-Wide 1/4" Steel Blade: Delivers maximum column stiffness to prevent tape collapse in wide conduit runs and long commercial pulls.
- Oil-Tempered Spring Steel: Formulated for high tensile durability and kink resistance while retaining flat memory.
- Integrated Case Viewing Port: Instantly view remaining tape footage inside the reel and quickly flush out dirt and drywall debris.
- Rapid Pay-Out & Rewind: Smooth reel mechanism combined with a comfort grip handle accelerates deployment and retrieval.
- Low-Profile Formed Eye: Designed with an offset bend that easily glides through standard fittings and conduit sweeps.

Frequently Asked Questions
Why choose a 1/4-inch wide fish tape over a standard 1/8-inch tape?
A 1/4-inch wide fish tape provides substantially greater column strength and rigidity. This prevents the tape from folding or buckling over long distances, making it ideal for pushing through large-diameter conduit and long commercial raceways.
What is the maximum pulling strength of the FTS438W-100?
The Greenlee FTS438W-100 has a rated maximum design tensile strength of 400 lbs (1.7 kN), providing plenty of pulling force for heavy wire and cable assemblies.
How does the case viewing port help during wire pulls?
The built-in viewing port allows you to see how much tape remains inside the reel at a glance, and also provides a convenient cleanout opening to blow or shake out accumulated jobsite dirt, drywall dust, and debris.
Can this tape be used in conduit with existing live wires?
No. Steel fish tapes are highly conductive. Always de-energize circuits and confirm with a reliable voltage tester before inserting metal fish tapes into panels, boxes, or conduits. For energized environments, use non-conductive fiberglass or nylon fish tapes.
