B-Line Eaton series fastener hardware and accessories, Designed for use in solid concrete, Stainless steel type 304 ,1⁄4", Used for overhead applicati

Yes. The ADI-25SS4 is type 304 stainless steel and is specified for overhead applications, which is what you want for threaded rod supporting conduit, cable tray, or pipe off a concrete deck. Type 304 gives you corrosion resistance that plain zinc-plated carbon steel anchors do not, so it suits parking decks, wash-down areas, and damp mechanical spaces.

The anchor body is 1 inch tall, so the hole has to be drilled at least that deep plus clearance for drill dust at the bottom. Drop-ins set flush with the concrete surface, so the embedment is the full 1 inch length of the anchor and the rod threads in from below.

Yes, the ADI-25SS4 carries a UL Listing, which is what most electrical inspectors want to see when anchors are carrying conduit, strut, or cable tray supports off a concrete deck.

No. Once the expansion plug is driven, a drop-in is permanently set in the concrete. You can back the rod out and thread a new one in, since the anchor's internal thread stays in the deck, but the 1 inch anchor body itself is not recoverable. Plan hanger layout before setting.

Yes. Drop-ins are designed to be set flush with the concrete face, so nothing protrudes until you thread in the rod or bolt. That lets you bring strut, a channel, or a mounting plate up tight against the deck, which is why this style gets used for overhead work instead of a wedge anchor that always leaves a stud sticking out.
