Anchors for wet concrete, also called cast-in-place anchors, are permanent anchors cast into a concrete surface. They are positioned in freshly poured concrete and lock into place as it dries. They are made with wings, fingers, and other features that increase their holding power in the concrete.
L-hook anchors, also called L-bolts, are placed into wet concrete and cast in place as the concrete cures. They feature a 90° bend on the unthreaded end that engages with the concrete and stops the anchor from pulling out or spinning when tightened. They are used to install plates, anchor columns into place, and secure other permanent loads.
