Product identity

Duck 373447 is a professional-grade electrical tape supplied as a single black roll. It is intended for electricians, maintenance technicians and DIY users who need reliable insulation for wiring repairs, splices and cable bundling.

Voltage and temperature limits

The tape is rated for continuous use up to 600 volts and across a temperature range from 14°F to 176°F. Its 7 mil vinyl construction provides flame-retardant and weather-resistant performance, so it remains effective in both indoor and exposed outdoor installations.

Installation notes

The vinyl stretches well and conforms to irregular shapes, allowing tight wraps around connectors and cable bundles. Clean, dry surfaces give the best adhesion; oil, dust or moisture can reduce bond strength. Applying the tape under slight tension and overlapping each turn by half the width helps avoid gaps that could compromise insulation.

Questions about this item

What width and length does the single roll of Duck 373447 electrical tape provide?

The roll measures .75 inches wide by 20 feet long, giving a single continuous length for wiring repairs or insulation tasks.

What does the 600-Volt rating mean when I use this tape on a live circuit?

It certifies the 7 mil vinyl insulation for electrical systems up to 600 Volts, so the tape maintains its dielectric strength at household and light-commercial voltages.

How does the 14 to 176-Degree F temperature range affect the tape's performance outdoors?

The adhesive and vinyl stay flexible and bonded from freezing winter lows at 14-Degree F through summer highs of 176-Degree F, preventing flagging or cracking in exposed runs.
