The 100 PK Arlington (441) 3/4" Plastic Insulating Bushing is designed to provide protection for wires when they pass through 3/4" conduit. To use, simply insert the bushing into the conduit at the entry point, ensuring it sits securely to prevent the wire from coming into contact with the sharp edges of the conduit. This insulating bushing helps protect the wire insulation from damage, reducing the risk of electrical shorts or faults. With a 105°C rating, it is suitable for use in high-temperature environments, making it ideal for residential, commercial, or industrial electrical installations. The plastic material ensures durability and safety while maintaining a secure and reliable connection.
