Technical Features
- 7 mil vinyl construction: Provides a durable, commercial-grade thickness that resists puncture and abrasion on wire and cable surfaces.
- 600-volt rating: Qualifies this tape for primary electrical insulation on standard low-voltage wire and cable splices.
- Temperature rating up to 194F: Maintains adhesion and insulating integrity in elevated-temperature environments such as junction boxes and conduit runs.
- Highly flexible, stretchy, and conformable vinyl backing: Allows the tape to conform tightly around irregular wire geometries and splice points, reducing air gaps in the wrap.
- UL Listed: Independently verified to meet applicable safety standards for electrical insulation applications.
- 3/4″ x 66′ format (1-Pack): Delivers an extended roll length suited for multiple splices or larger insulation tasks without mid-job roll changes.
Applications
- Primary electrical insulation for wire and cable splices up to 600 volts
- Holding, protecting, and insulating wire bundles and connections
- General-purpose electrical work in commercial and residential settings
