Stakes are 1-inch-diameter, schedule 40, galvanized, steel pipe with a welded eye. Stakes have a high-visibility red finish.

Tow bridles are used for anchoring or towing long, heavy curtain sections. Bridles come in four sizes, from 3 inches to 25 inches, to accommodate all ABASCO curtain sizes. Includes one aluminum connector, ASTM pin, welded doublers top and bottom, and 5/16-inch galvanized aircraft cable. Floats are optional.
