Professional PVC Heating Blanket 3 1 2 to 4 Inch by Greenlee
Greenlee 3-1/2 In. – 4 In. PVC Heating Blanket – 860-4
The Greenlee 860-4 PVC Heating Blanket is a professional heating tool designed to make bends, offsets, and saddles in 3-1/2-inch to 4-inch PVC conduit. It provides controlled, even heat to soften the PVC so it can be formed by hand into the required shape.
The blanket wraps around the conduit and is secured using a hook-and-loop strap. Built-in stiffeners help keep the heating surface in close contact with the PVC, promoting more uniform heating during the bending process.
Operating from a 120 VAC power source and rated at 1,300 watts, the 860-4 reaches temperatures above 300°F (149°C). Its heavy-duty power cord and thermostat are designed for durability during professional use.
Key Features
3-1/2 to 4-inch PVC capacity — Designed specifically for bending PVC conduit in this size range.
Controlled, even heating — Helps soften the conduit uniformly for consistent hand forming.
Hook-and-loop fastening strap — Secures the blanket around the PVC during heating.
Built-in stiffeners — Help keep the blanket tight against the conduit surface.
High operating temperature — Reaches temperatures above 300°F (149°C).
Heavy-duty cord and thermostat — Designed for long-term professional use.
Large heating surface — Measures 38 × 16-1/4 inches, providing coverage suitable for the supported conduit sizes.
120 VAC operation — Designed for use with a standard 120-volt AC power source.
Reusable design — Can be used repeatedly for PVC bending applications when properly maintained and stored.
Designed for PVC Bending
The 860-4 is intended specifically for PVC conduit bending. It can be used to create bends, offsets, and saddles without requiring a conventional rigid heating setup.
During operation, the blanket is positioned around the PVC at the desired bending location and secured with its hook-and-loop strap. Once the PVC becomes sufficiently flexible, the blanket is removed and the conduit can be formed by hand.
The manufacturer specifies the 860-4 for 3-1/2-inch and 4-inch PVC, covering all schedules within the stated capacity. Using the correct blanket size is important; Greenlee warns that heating PVC conduit smaller than the specified range can damage the blanket and void the warranty.
Uniform Heating
The blanket is designed to provide controlled and even heating across the PVC surface. Built-in stiffeners help maintain close contact between the blanket and conduit, which supports more consistent heat transfer during the softening process.
This makes the 860-4 useful when forming conduit directly on a jobsite or in a workshop where accurate bends, offsets, and saddles are required.
Easy-to-Use Wraparound Design
The heating blanket is positioned around the PVC and secured using the integrated hook-and-loop strap. Once the PVC has softened sufficiently, the blanket can be removed and the conduit formed by hand.
The design eliminates the need to heat the entire length of conduit, allowing heat to be concentrated around the area where the bend is required.

Greenlee's current specifications identify the 860-4 as a 120 VAC, 1,300-watt PVC blanket measuring 38 × 16-1/4 inches, with a 3-1/2 to 4-inch PVC capacity and a 16-inch bend radius. Greenlee documentation also lists the product weight as approximately 4.9 lb. (2.2 kg).
Recommended Bend Radius
For 3-1/2-inch and 4-inch PVC conduit, Greenlee's instructions specify minimum centerline bend radii of 21 inches for 3-1/2-inch conduit and 24 inches for 4-inch conduit. The manufacturer's general product specification lists a 16-inch bend-radius value, so the applicable minimum radius should be determined from the conduit size and the manufacturer's bending instructions rather than assuming 16 inches applies to every 860-4 application.
Professional Applications
The Greenlee 860-4 is suitable for professionals who need to form larger PVC conduit, including:
Electrical contractors
Commercial electricians
Industrial electrical installers
Utility contractors
Construction crews
Electrical maintenance teams
PVC conduit fabrication and installation
It is particularly useful for field applications where conduit must be shaped to follow specific installation routes.
Operating and Safety Considerations
The heating blanket reaches temperatures above 300°F (149°C). Greenlee instructs users to wear protective gloves when operating the blanket and forming PVC. The manufacturer also warns that the hot blanket should never be left unattended.
The blanket should be inspected before use and should not be operated if its surface is worn or torn. Greenlee also specifies that the blanket is intended only for heating PVC conduit and should not be used on other materials or for other applications.
Do not fold, bend, or crush the blanket during storage. Greenlee recommends storing it in its reusable pouch when it is not being used.
Why Choose the Greenlee 860-4?
The Greenlee 860-4 PVC Heating Blanket provides a practical way to form 3-1/2-inch and 4-inch PVC conduit using controlled heat and manual forming. Its wraparound design, integrated stiffeners, hook-and-loop strap, heavy-duty cord, and thermostat make it well suited to professional conduit-bending work.
With 1,300 watts of 120 VAC power and operating temperatures exceeding 300°F (149°C), the 860-4 delivers the heating performance required to soften large PVC conduit for bends, offsets, and saddles while remaining relatively lightweight at approximately 4.9 pounds.
