The ADE-50 is made for concrete, block, brick or stone. It's a double expansion anchor, so the shell expands at both ends as the bolt is drawn up, which spreads the grip over the full depth of the hole. That matters in softer or hollow-ish bases like block and brick, where a single-expansion shell concentrates all its load at the bottom of the hole.

The anchor body measures 2.5 in in height and 1 in in diameter, so plan on a 1 in hole drilled deep enough to take the full 2.5 in shell plus drill dust at the bottom. The slab or masonry has to be thick enough to accept that embedment, which is the usual disqualifier on thin toppings and hollow block faces.

No. It's an expansion anchor that has to bear against solid material around the hole, and it's specified for concrete, block, brick or stone. Set it in drywall or into an empty block cell and there's nothing for the shell to expand against. For hollow substrates use a toggle or a sleeve-type hollow-wall anchor instead.

Yes. Because the ADE-50 is internally threaded rather than a stud-type anchor, the bolt or rod backs out without disturbing the shell set in the concrete. That's the reason contractors pick this style for conduit hangers, strut, and equipment that gets pulled and re-hung later: the hole and anchor stay in place and you just re-thread a new bolt.

UL Listed, yes. The ADE-50 is part of Eaton's B-Line electrical fastener line, which is what specifying engineers and institutional inspectors usually want to see on anchors carrying conduit racks, cable tray, and panel supports.

The body is Zamac alloy, a zinc-aluminum die-cast material commonly used for expansion shells because it forms cleanly and resists the mild corrosion you get in interior slabs and mechanical spaces. For sustained wet, exterior, or chemically aggressive exposure, a stainless anchor is the better call.
