A flexible insert or guard has an elongated plastic body having a length to cover an opening of an electrical box and having two prongs or posts extending outwardly from the body for insertion into spaced apart mounting holes of the electrical box. The elongated plastic body flares outwardly at its ends in a region of the prongs and narrows along a center section to provide a gap between the insert and side walls of said electrical box wide enough to allow the insert to be removed after drywall is installed.

The invention claimed is: 1. A one piece injection molded plastic insert for engagement with an electrical box comprising an elongated body having a length to cover an opening of said electrical box and having two posts extending outwardly from the body for insertion into spaced apart mounting holes of said electrical box wherein the elongated body has two relatively wide flared out end regions that surround the posts and a narrower center section that has a uniform width of between one half inch and one inch and extends more than half the length of the plastic insert between the flared out end regions to leave a gap between the center section of the elongated body and side walls of said electrical box. 2. The plastic insert of claim 1 wherein the elongated body has a strengthening spine that extends along a portion of the elongated body. 3. The plastic insert of claim 2 wherein the elongated body defines a generally planar surface on one side and wherein the posts and strengthening spine extend out from the body along an opposite surface of the body from said generally planar surface. 4. The plastic insert of claim 1 wherein a length of the posts ranges from ⅛ inch to ⅜ inches in length. 5. The plastic insert of claim 1 wherein the posts are generally cylindrical and include spaced apart flanges extending along a portion of a posts near the elongated body having outer surfaces that engage inner walls of threaded openings of an electrical box. 6. A one piece injection molded plastic insert for engagement with an electrical box comprising an elongated body having a length to cover an opening of said electrical box and having two posts extending outwardly from the elongated body for insertion into spaced apart mounting holes of said electrical box wherein the elongated body has two relatively wide flared out end regions that surround the posts and a narrower center section that has a uniform width that extends between the flared out end regions dimensioned to leave a gap between the center section of the elongated body and side walls of said electrical box. 7. The plastic insert of claim 6 wherein a width of the center section along at least a portion of the elongated body is in a range of from ⅜ inch to 1 and �� inches. 8. The plastic insert of claim 6 wherein the center section has a uniform width that extends over more than half of the length of the insert in a region between end walls of the electrical box and wherein the uniform width is between about one half inch and one inch.
