This PVC Conduit heating blanket by Gardner Bender® is a convenient solution for bending PVC conduit from 1/2" to 4". Instead of inserting your conduit into the unit, this blanket is wrapped around the conduit for easy positioning. Heat is regulated by a thermostatic control that responds to your environment, ensuring fast heating and safe temperatures in any environment.

  • Ideal for creating turns and bends for use in electrical, telecom, and plumbing applications
  • Unlike hot box type benders, the HotBlanket is compact in size and can be easily transported from jobsite to jobsite
  • Available plug set supports the inside of the conduit to prevent deformities while heating
  • Multi-circuit design and heavy gauge wire extends its service life far beyond that of other heat blankets
  • Heats to a temperature that won't scorch or burn conduit for increased personnel and fire protection
