Metallics 1PSC75 Strut Clamp 1 pc 3/4" - 1/2" (Box 50)

That's exactly what the 1PSC75 covers. It is a one piece strut clamp sized 3/4 inch to 1/2 inch, meaning it takes 3/4 inch EMT or 1/2 inch rigid conduit, which share the same outside diameter. The description states it is built for EMT and rigid conduit, and the wide saddle also supports cable and pipe of that same diameter.

Only where you are mounting to strut channel. A strut clamp like the 1PSC75 snaps into the lips of a channel run, so it works on trapeze hangers and strut racks, not on bare drywall, block or deck. If you are fastening directly to a wall or ceiling surface, use a one hole or two hole conduit strap with an anchor instead. Where you have multiple parallel runs, strut plus clamps is the usual way to carry them on one hanger.

A screwdriver or nutdriver is all it takes. The 1PSC75 is a single piece design with no separate screws or bolts, so nothing drops off a lift or into a ceiling grid while you are running conduit overhead. That is the main reason crews pick a one piece clamp over a two piece strut strap with a channel nut and bolt.

The 1PSC75 ships as a box of 50 clamps, and 50 count is the order minimum, so a box is the smallest buy. Metallics does make other sizes and quantities available by request if your run needs a different trade size.

Steel with a galvanized finish. That zinc coating is the standard choice for indoor mechanical spaces, utility rooms and covered garages where moisture is present but the clamp is not sitting in weather or a corrosive wash down. For continuous exterior or chemical exposure, specify a stainless clamp instead.

Yes, the 1PSC75 is listed as both Buy American compliant and ARRA compliant, which is what institutional and government procurement typically needs on the submittal. Country of origin is recorded as multiple, so if your contract requires a single named origin on the certification, ask for documentation on the lot you receive.

The saddle on this clamp is soft and wide, so the bearing load spreads out rather than pinching a single point. That matters most when you are supporting cable or thin wall tubing on the same strut run as rigid conduit.

A box of 50 is listed at 3 lbs, with carton dimensions of 7.25 x 6.75 x 3.25 inches. Small enough to carry several boxes in a tool bag when you are stocking a van for a conduit run.
