Specifications

Application
Compression style connector with internal sealing ring and knockout gasket to create a raintight seal when connecting EMT to box or enclosure. With Bridgeport’s newly redesigned Raintight Compression Connectors, 256-RTI2 thru 259-RTI2, contractors can install just one wet location fitting for either thread less Rigid / IMC or EMT. These 3-1/2” dual Listed Zinc Alloy fittings come standard with a 105° C temperature rated insulated throat and the words “Rigid / EMT and RAINTIGHT” clearly cast into the body. This marking helps the AHJ to precisely confirm the products intended use.
