EMT set-screw coupling · 2-1/2 in trade size · steel body · Hubbell SKS250
What this product is for
This 2-1/2 in trade size EMT set-screw coupling is used to join two lengths of electrical metallic tubing (EMT) and maintain a continuous raceway path. It is a steel coupling intended for dry-location conduit runs in commercial, institutional, and industrial installations.
Use for
- Joining 2-1/2 in EMT conduit
- Indoor branch circuit and feeder raceways
- Service rooms, plant areas, commercial ceilings, and exposed conduit runs in dry locations
- Maintenance, retrofit, and new construction work where EMT is already specified
Avoid for
- Wet or raintight applications unless the full fitting system is specifically listed for that use
- Threaded rigid or IMC connections that require a threaded coupling
- Installations where concrete-tight or compression-style performance is required by spec
Best for
Best for electricians and contractors needing a standard large-trade EMT coupling that installs with set screws rather than compression hardware. This style is commonly chosen where speed of installation and compatibility with EMT runs matter more than raintight performance.
Installed in
Typically installed in dry indoor conduit systems in commercial buildings, light industrial facilities, schools, retail spaces, and mechanical or electrical rooms. The trade size is 2-1/2 in (63 mm nominal).
Why this product exists
It provides a simple mechanical connection between two EMT sections so conductors remain protected inside a continuous metal raceway. For larger conduit sizes, a set-screw coupling can help simplify alignment and field assembly during installation.
Compared with similar products
Compared with compression couplings, a set-screw coupling is typically selected for dry locations and faster installation. Compared with threaded rigid or IMC couplings, this fitting is intended for EMT rather than threaded conduit. As a rule of thumb, conduit fill should still be checked for the complete raceway system, and actual suitability depends on installation conditions and local electrical code.
