Metallics JCPT1 Anchors 3/8 Tog Ancr Plas (Jar 100)

No. The JCPT1 is a 3/8 plastic toggle, which needs an open cavity behind the wall to let the wings deploy. In solid concrete or solid masonry there is nowhere for the toggle to open, so it will not set. For solid concrete you want a sleeve or wedge anchor, or a plastic expansion plug sized to the drilled hole, instead of a toggle.

The Metallics JCPT1 is a 3/8 inch plastic toggle anchor, packed 100 to a jar. Ordering is by the jar rather than loose count, so one unit gets you the full 100 pieces for a panel or fixture run.

A plastic toggle like the JCPT1 is for hollow wall work: drywall, plaster, and hollow block where there is no stud behind the fixing point. The plastic wings fold through the hole and spread behind the panel, so the load is carried by the back face of the board instead of the hole itself. Metal toggle bolts handle heavier pull-out loads and are what you move to for suspended equipment or anything carrying real weight. For box mounting, device plates, raceway, and light fixture straps, the plastic toggle is the normal choice.

Yes, they are catalogued by Metallics as electrical fasteners, the same jar-pack anchors an electrician carries on the van for mounting boxes, straps, and plates to hollow walls. Nothing about the anchor restricts it to electrical use, but that is the trade the pack size and stocking are built around.

A 3/8 designation on a plastic toggle refers to the anchor body that passes through the wall, so the hole is drilled to match the 3/8 body and the anchor is pushed through until the collar seats flush on the face of the board. Do not oversize the hole, or the collar loses its bearing and the anchor spins instead of drawing tight.
