Steel City ZCC1/23/4H1/4-3 Clip, Flange Vertical Mount Conduit

The ZCC1/23/4H1/4-3 conduit clip covers 1/2 inch to 3/4 inch conduit. One clip handles both trade sizes, so a run that steps from 1/2 to 3/4 can be supported with a single part number rather than two.

It is a vertical mount conduit clip that grips a flange, so the conduit is held off existing steel or a trapezoidal ceiling flange rather than off a drilled anchor. No concrete anchoring, no strap and screw into deck. That makes it a fast pick where you already have structural steel or a trapezoidal ceiling profile to grab, and the wrong pick where you have nothing but bare concrete or drywall to fasten to.

That is exactly what it is built for. The part is classed as a hanger for trapezoidal ceiling, and it clips to the flange of the deck profile to carry 1/2 or 3/4 inch conduit vertically. Where you have flat concrete overhead instead, you want a beam clamp or a rod and strap assembly, not this clip.

Steel with a black zinc phosphate finish. Zinc phosphate is a coating that gives moderate corrosion resistance for dry interior and protected unfinished spaces, parking structures, mechanical rooms. It is not a galvanized or stainless part, so for exterior exposure, wash-down, or a corrosive process area, spec a hot dip galvanized or stainless clip instead.

It classifies as UNSPSC 39121701, electrical hangers. Institutional and government buyers coding a requisition can drop that straight into the line item for this clip.

Black, from the zinc phosphate coating. In an exposed structure ceiling that already reads dark it disappears reasonably well without painting, which matters on retail and hospitality jobs where the deck is left open.
