3-Inch EMT Bushing

The DOTTIE EMTB300 is a snap-on polyethylene bushing designed for three-inch electrical metallic tubing. It provides a smooth, protective surface at conduit ends to prevent cable insulation damage during pulling. The white polyethylene construction resists moisture and corrosion in standard electrical installations. Electricians and maintenance technicians use it to finish conduit runs in commercial and residential wiring projects.

Conduit Compatibility Check

Verify that the installed conduit is three-inch EMT before ordering this bushing. The snap-on design fits only the outside diameter of standard three-inch electrical metallic tubing. Confirm the conduit end is cut square and free of burrs so the bushing seats fully. This item is not intended for rigid metal conduit, PVC or flexible conduit types of any size.

Installation Integration

The bushing presses onto the conduit end by hand with no tools required, freeoring up installation time on the job site. Once seated it stays in place without set-screws or adhesive, allowing cables to slide through the protected opening. It works alongside standard EMT couplings, connectors and straps to complete a code-compliant raceway system.
