Abstract
An anchor for being embedded in concrete for attachment to a fastener to support a load comprises a plug having a main body portion extending upwardly from a base portion, the plug for being attached to a form board prior to pouring of concrete, the plug having an end portion disposed a distance from the form board; and an anchor body attached to the end portion. The plug is separable from the anchor body and removable from the concrete after the concrete is cured, leaving the anchor body embedded in the concrete, the plug providing a void in the concrete after removal to provide an access opening for a threaded portion of a fastener to attach to the anchor body.

A plug, comprising:
- a) a body for attachment to a form board prior to pouring of concrete, the body including an end portion disposed a distance from the form board;
- b) a helical member disposed at the end portion;
- c) the body for being removable from the concrete after the concrete is cured and separable from the helical member to leave the helical member in the concrete, the body for providing a void in the concrete after removal from the concrete to provide an access opening for a a fastener for attaching to the helical member in the concrete.
A plug, comprising:
- a) a body for attachment to a form board prior to pouring of concrete, the body including an end portion disposed a distance from the form board;
- b) the end portion including a first circumferential groove and a first ring partly disposed in the groove, the first ring for molding a second circular groove in the concrete;
- c) the body and the first ring for being removable from the concrete after the concrete is cured for leaving a mold of the first ring in the concrete, the body for providing a void in the concrete after removal to provide an access opening to the second circular groove for attachment of a fastener.
A plug, comprising:
- a) a body for being attached to a form board with screws and/or nails prior to pouring of concrete, the body including an end portion disposed a distance from the form board, the end portion for positioning an anchor body in the concrete;
- b) the body being configured to allow the screws and/or nails to remain attached to the form board when the form board is removed;
- and
- c) the body providing an opening through the concrete for access to the anchor body after the form board is removed after the concrete is cured.
