Reducing Bushing · 1 in x 1/2 in - Threaded Steel - Zinc Plated - Appleton RB100-50
SKU: CF-RB1X1/2
Threaded reducing bushing for reducing a 1 in conduit entry to 1/2 in in rigid and IMC conduit systems. Steel body with zinc electroplated finish and an integral smooth bushing to help protect conductor insulation.
What this product is for
This threaded reducing bushing is used to reduce a 1 in trade size threaded conduit opening to 1/2 in for rigid and IMC conduit systems. It is commonly selected where an enclosure, hub, or fitting has a larger threaded entry than the conduit being installed.
Use for
Use for threaded rigid metal conduit and IMC installations in commercial, industrial, and service work. It is suitable where a smooth integral bushing is needed to help protect conductor insulation at the transition point.
Avoid for
Avoid using this part on non-threaded raceway systems or where a reducing washer, adapter, or different fitting style is required by the enclosure or installation method. Confirm thread type, trade size, and certification requirements before ordering.
Best for
Best for electricians reducing a 1 in threaded hub to 1/2 in without changing the enclosure or conduit body. This style is a practical choice for retrofit work, panel entries, and threaded fittings where conductor protection matters.
Installed in
Typically installed in threaded hubs, conduit bodies, boxes, and enclosures used with rigid conduit or IMC. Common in indoor commercial and industrial electrical systems.
Why this product exists
It allows a larger threaded conduit entry to accept a smaller conduit size while maintaining a threaded connection. The smooth rounded bushing helps reduce the chance of conductor insulation damage during pull-in.
Compared with similar products
Compared with reducing washers, a threaded reducing bushing is used where the fitting or enclosure has a threaded entry. Compared with adapters, this part is a compact option when only a size reduction is needed. Always match the fitting style to the raceway system and enclosure entry.
