Davis Instruments' MiniShockle is a superstring black bungee that comes in 12 inches, 18 inches and 24 inches. Prices start at $13.99. The wire gate snaps, on each end, are 316 stainless steel so they won't rust or corrode and the MiniShockle can hold 300 pounds, which is about 10 times the strength of a standard bungee.
