Minerallac 294 – Frequently Asked Questions

1) Will a Minerallac 294 strap fit 3 inch rigid conduit as well as EMT?
Yes. The Minerallac 294 two-hole strap is sized for 3 inch trade size and fits both 3 inch EMT and 3 inch Rigid/IMC. The trade size marking is what matters here, not the outside diameter, so one strap covers both conduit types on a 3 inch run.
2) Are screws or anchors included with the Minerallac 294 conduit strap?
No fasteners come with it. The strap is the stamped steel piece only, and you supply hardware to suit the surface: wood screws into framing, self-drillers or bolts into steel, and sleeve or wedge anchors into concrete. Minerallac lists wood, steel, concrete, and component mounting as the intended methods, so the fastener choice is yours to make per substrate.
3) When should I use a two-hole conduit strap instead of a one-hole strap?
Use the two-hole type when the run is heavy or the strap is carrying load the single-hole version can't. The Minerallac 294 puts a fastener on each side of the conduit, so the load is split across two anchor points rather than cantilevered off one. At 3 inch trade size the conduit itself is heavy enough that most commercial and industrial runs, and anything vertical or overhead, get the two-hole strap. A one-hole strap is fine for small trade sizes on light horizontal runs.
4) How far apart are the mounting holes on the Minerallac 3 inch two-hole strap, and how much room do I need on the mounting surface?
Plan the layout off the overall strap length: the 294 measures 7.438 inches long, 1.250 inches wide, and 3.550 inches high. That 7.438 inch footprint is what has to land flat on your backing, so a narrow 2x4 flatwise or a tight strut face will not take it without the ends overhanging. The two holes sit near each end of that length.
5) Is a zinc plated steel conduit strap OK outdoors or in a damp area?
Zinc plated steel is a general-purpose indoor and protected-location finish. It resists corrosion in normal building environments, but plating is thin compared to hot-dip galvanizing, so direct weather exposure, wash-down areas, coastal air, or corrosive process environments will attack it over time. For those, specify a galvanized or stainless strap instead. The 294 is steel with a zinc plated silver finish.
6) Can I use the Minerallac 294 to replace an existing single-hole strap on a 3 inch conduit run?
That upgrade works, with one caveat on layout. The two-hole strap needs a second fastener, and the existing single hole almost never lines up with either of the new hole positions. Expect to drill or anchor two fresh holes per support point across the 7.438 inch footprint, and make sure the backing is wide enough to take both. The conduit itself does not need to come down if you can slip the strap over it.
7) What part number do I order for the Minerallac 3 inch two-hole strap?
Order Minerallac 294. That is the manufacturer part number for the 3 inch trade size two-hole strap in zinc plated steel. Minerallac's two-hole straps run as a numbered series by trade size, so confirm you want the 3 inch before ordering, since the adjacent numbers are different sizes.
8) Is the Minerallac 294 conduit strap made in the USA?
Yes, it is manufactured in the United States. That matters on public works, federal, and institutional jobs carrying Buy American or domestic-content language in the specification, where an imported strap can get a submittal kicked back.
