ABSTRACT:
Environmentally employable in combination with a slidable-door type open-wall and for maintaining an angular-dog type slidable-door in tight opening-obstructed temperature-protective contact adjacently about the wall-opening of a said upright open-wall, a floor-mountable retractable roller device including a floor-mountable horizontal base-plate and including a pivotably mounted elongate rear-arm having a rotatable horizontal-roller springably urged toward the slidable-door underlying angular-dog to temperaturely-protectively urge the slidable-door in closure-condition about the wall-opening. The springably urged force between the slidable-door lower angular-dog and the device horizontal-roller can be empirically adjusted with an adjusting screw disclosed herein.
