Abstract
Abstract This is a universal, re-usable system to accurately locate and temporarily hold an element to-be-embedded in concrete in a form. The system includes at least two rails and at least one element locating plate. The plate is capable of being attached in combination with and supported by the rails at any point along their length, while the rails supporting the plate are capable of being located at any position on a concrete form, so that an element locating plate and the related work element are capable of being accurately positioned at any location within the form. In preferred embodiments the to-be-located element is an anchor bolt and the plate defines at least one opening of a size which allows the bolt to be inserted through the plate.
