Lift-The-DOT® Washer is a strong, heavy-duty brass fastener with a black finish that can be used in cloth-to-cloth applications. Lift-The-DOT fasteners lock on three sides and are opened by lifting the fourth side where the dot and trademark appear. The washer secures to the bottom of a 2 Prong Stud (sold separately). An installed socket and backplate snap onto the installed stud and washer. These fasteners are often used to secure boat covers and dodgers.
