Abstract
A pulling iron enclosure is provided for recessing a pulling iron in a wall of an underground vault. The enclosure is defined by a base and a removable cover. The enclosure has a cavity therein with the cover overlying one side of the cavity. A wall of the enclosure has an opening through which a pulling iron may extend for positioning the pulling iron in the cavity so that the pulling iron will be readily accessible in said cavity when the enclosure and pulling iron are embedded in a wall of the vault.
