Nonconductive Fish Tape for Runs with Bends

1/8" Tape Diameter

3/16" Tape Diameter

Safer to use around energized equipment than other types of fish tape, this fiberglass tape is also round, making it more flexible than flat and oval tape to pull wire through multiple bends. Attach your wire to the tape and push it through conduit and raceway.

1/8" dia. tape comes with leaders that help guide the tape through conduit bends. It also includes replacement parts and adhesive, which can be used to repair the tape.

Nonconductive Fish Tape for Long Runs

Thicker than standard fish tape, this fiberglass tape remains stiff along its entire length for long runs of conduit and raceway. It’s nonconductive, so it’s safer to use around energized equipment than metal fish tape. Attach your wire to the tape and fish it through. Round and flexible, this tape handles making multiple bends in different directions. It’s also known as conduit rodder.

Fiberglass Weld-Backing Tape

Stick this flexible tape to the back of welding seams to contain spatter and prevent oxygen, water vapor, and other gases from weakening the weld. Also known as back purge tape, it’s used for welding flat sheets, large tanks, and other applications where filling the space behind the seam with purge gas is difficult or expensive. Form the fiberglass spine into a small ridge over the weld joint, then press the adhesive foil down on each side. Compatible with MIG, TIG, and stick welding.

Apply 200 amp tape to thin welds on aluminum, cast iron, nickel and copper alloys, and steel.

Use 600 amp tape to shield thick welds on dense metals, such as stainless steel.
