SEPCO 135 – Frequently Asked Questions

1) What size conduit does the SEPCO 135 strap fit?
The SEPCO 135 is sized for 1-1/4 inch trade size conduit. Trade size is not the same as the actual outside diameter, so match it to the marked size on your conduit rather than measuring the pipe. A strap one size off will either not close on the raceway or leave the run loose at the mounting point.
2) Do conduit straps come with mounting screws or anchors?
No fasteners come with the 135. The one-hole design takes a single screw or anchor you supply, chosen for the substrate: wood screws into studs and blocking, self-drilling screws into metal framing, and sleeve or wedge anchors into concrete and masonry. Order the anchors with the straps so the crew is not short on the wall.
3) Can I use the SEPCO 135 malleable iron strap with EMT, or is it only for rigid conduit?
The 135 is described as securing rigid and other compatible conduit runs. Since one-hole straps are sized by trade size, a 1-1/4 inch strap pairs with 1-1/4 inch raceway of the type it is rated for. If you are strapping 1-1/4 EMT, confirm the raceway type you are supporting matches rigid-style strap sizing before you buy a box for the job.
4) Is a malleable iron conduit strap worth it over a stamped steel one?
Malleable iron is the heavier-duty choice. The 135 body resists impact, bending, and deformation both while you are driving the fastener and over years in service, where a thin stamped strap can distort and let the run shift. For a 1-1/4 inch feeder on an industrial wall or exposed structural steel, iron is the one you want; light stamped straps are fine for small-diameter branch runs indoors.
5) Will a zinc-plated conduit strap hold up outdoors or in a wet area?
The zinc plating on the 135 protects the iron against rust in indoor and moderately exposed environments. That covers mechanical rooms, parking structures, and sheltered exteriors. For continuous weather exposure, direct chemical contact, or coastal salt air, specify a hot-dip galvanized or stainless support instead.
6) Can I mount a one-hole strap on a ceiling or overhead structural member?
Yes. The 135 is intended for walls, ceilings, studs, and structural framing, and it mounts flat against the surface with one fastener. Overhead, the fastener carries the whole load, so size the anchor to the weight of the filled 1-1/4 inch run and keep support spacing per the code requirement for the raceway type you are installing.
7) Is a one-hole strap the right support for a long horizontal conduit run, or should I use trapeze or unistrut?
One-hole straps like the 135 are for fastening conduit directly to a surface, wall, ceiling, stud, or structural member, one fastener per strap. They keep a run aligned and evenly spaced where there is solid backing to hit. If the conduit has to stand off from the structure, cross open space, or carry several parallel runs together, use channel and conduit clamps or a trapeze hanger instead.
8) What is the part number for the SEPCO 1-1/4 inch one-hole conduit strap?
Order it as SEPCO model 135. It is the zinc-plated malleable iron one-hole strap in 1-1/4 inch trade size. Keep that number with the size when ordering, since one-hole strap families run through many trade sizes under adjacent numbers.
9) Can I reuse one-hole straps on a retrofit where I'm replacing conduit?
The 135 is intended for both new installations and retrofit work, and it is a one-piece strap with no assembly, so it goes back on with a single fastener. Just keep the trade size matched: a 1-1/4 inch strap will not hold a different size raceway properly even if the existing hole lines up.
