Metallics J1120 Anchors 9/16 X 2-1/2 Blk Collarless An (Jar 50)

The J1120 is a 9/16 by 2-1/2 inch collarless anchor in black finish. The 9/16 inch is the anchor body diameter, so your hole in the concrete or masonry has to be drilled to that diameter, and 2-1/2 inches is the anchor length, which sets the minimum embedment depth you need in the base material.

Each jar holds 50 anchors. Metallics packages the J1120 in jar form rather than loose or bulk carton, which is the usual format for a service van or a shop shelf where you are pulling a handful at a time.

Collarless means the anchor body has no lip or flange at the top, so it seats fully down inside the drilled hole instead of standing proud of the surface. That matters when you are mounting something flat to concrete, block or brick, a strut channel, a box, a hanger, since a collar would hold the fixture off the wall. The J1120 is the 9/16 by 2-1/2 inch black collarless version.

Order Metallics J1120. That single number covers the 9/16 by 2-1/2 inch black collarless anchor supplied 50 to a jar, so there is no separate size or finish suffix to add.

Yes. It is carried as an electrical fastener, the kind of anchor an electrician uses to hang strut, conduit straps, boxes and equipment off concrete or masonry. Nothing about the anchor restricts it to electrical use, but that is the trade it is stocked for.
