A system configured to anchor a cover plate over an interface formed between substantially coplanar substrates includes a sleeve capable of being anchored in a first substrate; a spring located in the sleeve; a post located in communication with the spring; and a fastener secured onto the post. A head of the post is located in the sleeve, and an end of the post opposite the head of the post extends out of the sleeve to receive the fastener. The fastener is secured onto the post over the cover plate located on the first substrate such that the cover plate extends over the interface formed between the first and second substrates when they are positioned to be substantially coplanar.
