ABSTRACT:
A cast-in-place pass through firestop device for providing a passage in a partition in a structure through which wires, cables, pipes, and the like are run includes a housing having a riser portion with frangible connections that define removable bands that can be readily removed by a user to adjust the height of the device in accordance with the thickness of the partition into which the device is installed. The removable bands include pull tabs that provide grasping means to facilitate removal of the bands by a user along a frangible connection. The housing also includes a base portion including a recess with ribs for maintaining the firestop material in spaced relation from the base portion sidewall.
