Insert void forming device

Abstract

This invention relates to a device for forming a pre-set void in a floor, wall or other structural member, to thereby define an essentially integral spatial void or closure therein, which maintains the UL fire rating of the floor or other structural member in which it is positioned, and which may be readily removed, when desired, to define the void, without use of special tools or procedures. The device is useful for defining modular or other openings to receive, for example, insert devices, through which cables, such as power and telephone lines, may be passed from a source, for connection with fixtures, phones and other devices. The device is adapted to be secured to forms, for example so that a material such as cement or other floor, wall or other structural forming materials may be positioned or poured thereon and therearound; the device in such cases may form a preset-sealed part of the structural member, readily available for opening when desired.
