Sea-Dog Spring Hook 155630-1, 4-1/16 Inch, 1,200 lb Breaking Strength, Electro-Galvanized Steel

The Sea-Dog Spring Hook 155630-1 is a spring-loaded connector built for quick, one-handed hookups wherever a secure, releasable connection is needed aboard a boat or around the dock. The spring-loaded gate opens under light thumb pressure and snaps closed automatically, letting you clip and unclip lines, fenders, covers, and gear without tying or untying knots. It is rated to a 1,200 pound breaking strength, making it suitable for a range of load-bearing and utility applications beyond light-duty tie-downs.

Construction is electro-galvanized formed mild steel, a plating process that coats the steel in zinc to resist corrosion in wet and salt-air marine environments while keeping the hook strong enough for its rated load. The hook measures 4-1/16 inches overall (dimension A), with a width of 1 inch (dimension B) and an opening dimension of 1/2 inch (dimension C), and weighs 0.262 pounds. It ships in a standard pack quantity of 10 each, making it a practical choice for shops and boat owners who need multiples on hand.
