Description
Listed items are standard, but custom sizes can be made!
These stepped couplers are a variation of our external reverse threaded aluminum coupler described in another section and are used to connect two different sizes of innerduct.
The buttress thread form, pull out strength, and overall design of the stepped coupler is the same as external thread-on couplers. The couplers can be made to fit any two sizes or types of HDPE specified by the customer.
