3-1/2 Inch EMT Conduit Hanger
The L.H. Dottie PH350B hanger secures 3-1/2 inch Electrical Metallic Tubing runs in commercial and residential installations. Its steel body with zinc plating resists corrosion on indoor and covered outdoor jobs. Electricians fasten the single-hole mounting strap to framing or strut channel with standard hardware. The rigid design holds conduit alignment through vibration and thermal cycling.
Electrical Contractors and DIY Installers
This hanger suits crews pulling EMT for power or low-voltage circuits who need code-compliant support spacing. It is not for buyers who want a clamp that also grips flexible metal conduit or rigid PVC without a separate adapter. Installers requiring a two-hole strap for heavier load distribution should look at a different mounting style.
3-1/2 Inch Trade Size Fit
The hanger is manufactured for 3-1/2 inch trade size EMT, matching the conduit outside diameter used on large feeder runs. Selecting the correct trade size prevents loose fits that fail inspection and over-tightening that crushes the tubing wall. No other diameter works with this specific model.

Questions about this item
What size EMT conduit does the 3-1/2 in hanger accommodate?
The 350B hanger is sized for 3-1/2 inch EMT conduit, matching the trade size marked on the conduit itself.
Can the zinc-plated steel hanger be used with older galvanised rigid conduit of the same trade size?
Yes, the 3-1/2 inch saddle fits any conduit with that outside diameter, so legacy rigid pipe works if the diameter matches.
How can I confirm the hanger is installed correctly after mounting?
The conduit should sit firmly in the saddle with no lateral movement, and the mounting bolt should be tight against the surface.
