A first void of the base portion runs through the base portion and is configured to admit a nozzle of the thermal breaching device. A first end of the retracting portion is configured to retractably seat onto the second end of the base portion. A second void of the retracting portion is configured to admit a portion of the nozzle that extends through the base portion. The second void runs through the retracting portion. The retracting portion comprises a slot dimensioned for receiving at least one of a plurality of target objects. The biasing element is configured to draw the first end of the retracting portion toward the second end of the base portion.
