Meet the Jandorf 1/2 in. Rubber Bushing, a compact two-pack built to guard wires and cables where they pass through panels, boxes, and enclosures. Designed with insulating rubber, this pair delivers reliable protection in tight spaces while maintaining flexibility for precise fits. It’s the practical, codes-friendly choice for DIY projects and professional electrical work alike.
What you get
- 2 x rubber bushings in carded packaging for easy retail display and straightforward installation
- Trade size: 1/2 inch
Key specifications
- Inside diameter (bushing bore): 3/8 in
- Outside diameter: 1-1/4 in
- Thickness: 0.56 in
- Material: Rubber

Why this matters
Plain metal bushings can transmit vibration and abrade conductors over time. These rubber bushings cushion wires as they pass through knockout holes, reducing wear at the entry point and providing a forgiving seal that accommodates minor misalignments. The rubber’s inherent insulation properties help isolate the conductor from enclosure edges, contributing to safer, longer-lasting installations.
Ideal use cases
- Entry points for wires and cables in electrical panels, control boxes, and small enclosures
- DIY electrical projects where a 1/2 inch trade-size bushing is required without metal hardware
- Retrofit jobs where a flexible, insulating bushing helps protect existing conductors
Installation tips
- Confirm the knockout hole corresponds to the 1/2 inch trade size specified
- Insert the bushing into the panel or enclosure opening until it seats firmly
- Feed the conductor or cable through the bore, using a light lubricant if needed to ease passage
Who should consider this
electricians, contractors, and handy homeowners working with standard 1/2 inch conduit entries or cable penetrations who value a reliable, insulating rubber solution that’s easy to install and provides gentle protection against cable wear and abrasion.
