SEPCO 139S Zinc Plated Steel 1-Hole Click-On Conduit Strap, 3-Inch

The SEPCO 139S is a 3-Inch, one-hole click-on conduit strap built from zinc plated steel for reliable corrosion resistance in commercial and industrial electrical installations. Designed for fast, tool-minimal mounting, this strap secures conduit runs to walls, ceilings, and structural framing without the fuss of traditional two-hole straps. The durable zinc plated finish helps the strap resist rust and wear over time, making it a dependable choice for both new construction and retrofit wiring projects. Electrical contractors rely on straps like the 139S to keep conduit runs neat, properly supported, and code-compliant, reducing the risk of sagging or shifting conduit over the life of an installation.

Key Features

  • Trade Size: 3-Inch strap sized specifically to secure 3-inch conduit runs with a snug, supportive fit.
  • Durable Construction: Zinc plated steel body resists corrosion, rust, and general wear for dependable long-term performance in demanding job-site conditions.
  • 1-Hole Click-On Design: A single-hole, snap-in mounting style speeds up installation considerably compared to conventional two-hole straps that require separate fasteners and alignment.
  • Finish: Zinc plated finish provides an added layer of surface protection against moisture and environmental exposure.
  • Straightforward Mounting: The click-on profile allows electricians to attach the strap directly to the conduit before fastening to the mounting surface, saving time on repetitive strap installations.

SEPCO 139S – Frequently Asked Questions

1) Will the SEPCO 139S conduit strap fit 3-inch rigid, IMC, or EMT conduit?
The 139S is sized for 3-inch trade size conduit and is used on rigid, IMC, and EMT runs. It is a single trade size only, so a 2-inch or 4-inch run needs the matching size strap instead, not this one.
2) What is the difference between a 1-hole click-on conduit strap and a standard two-hole strap?
A click-on strap like the SEPCO 139S snaps onto the conduit first, then fastens through a single hole to the surface. A two-hole strap needs two fasteners aligned on either side of the conduit. On long repetitive runs the one-hole click-on cuts the fastener count and the alignment work in half; two-hole straps are the choice where you want the extra bearing point against movement.
3) Is a zinc plated steel conduit strap okay for damp or outdoor-exposed locations?
The 139S is zinc plated steel, which gives corrosion and rust resistance for general commercial and industrial exposure, including moisture contact on walls and structural framing. Zinc plating is a surface coating though, so for continuously wet, coastal, or chemically aggressive areas most electricians step up to stainless or PVC-coated supports.
4) Do I need to buy screws or anchors separately for the SEPCO 139S strap?
Yes. The 139S provides the single mounting hole; the fastener is chosen to suit the surface, so you supply it. Wood or metal framing takes a screw, concrete or block takes an anchor, and strut mounting takes a strut nut and bolt. Order the anchors with the straps so the run does not stall.
5) Can one-hole straps be used to support a 3-inch conduit run on a ceiling?
The 139S is intended for conduit support on walls, ceilings, and structural framing. On overhead 3-inch runs the weight of the raceway plus conductors is the governing factor, so the anchor into the deck or framing has to carry the load and the spacing between straps has to follow the support interval your code requires for the raceway type.
