You can install it through the fixture. The AWA-50-700 is built so the anchor drops through the mounting hole in your strut, bracket, or base plate and into the drilled hole beneath, which means you can use the fixture itself as the drilling template instead of laying out holes separately. That is the main time saver on overhead trapeze and equipment-base work.

It is UL Listed. That matters on electrical installations where the inspector wants listed support hardware for raceway, cable tray, and equipment mounting rather than a generic hardware-store anchor.

The AWA-50-700 is zinc plated carbon steel. Zinc plating is a mild corrosion coating intended for dry interior use; it is not stainless and it will corrode in wet, washdown, coastal, or chemically aggressive locations. For exterior or damp environments, specify a stainless steel wedge anchor instead.

A wedge anchor such as the AWA-50-700 is a one-piece stud with an expansion clip; you drill, hammer it in, and tighten the nut to set the wedge, and the threaded stud stays proud of the concrete to take your fixture. A drop-in anchor sits flush and is internally threaded, so the bolt can be removed and the fixture taken off without disturbing the anchor. A sleeve anchor is for block and brick as well as concrete and gives lower holding values. Use the wedge anchor in solid cured concrete when you want maximum hold and do not need a removable, flush fastener.
