Designed for blocking drafts between dock seals and dock levelers, each blocker bag is constructed of heavy duty vinyl for superior durability. Draft-blocker bag is filled with foam for compressibility and air vents allow the bag to return to its original shape. Heavy weighted base provides excellent sealing action. Bag includes integral grommets to tether in place (attachment not included) and carrying handles for easy removal. Safety yellow stripes offer high visibility.
