This is the oar lock you've been waiting for. The cobra's wide horns have greater load area for much less stress on the oar-lock horns and increased durability. The elongated, oval opening allows for an additional 10-15 degrees of vertical range while keeping your oars snug in the locks. Made of a specially formulated bronze alloy for superior strength and proven by professionals throughout the world. Deluxe models are threaded with a lock-nut keeper to reduce play. Oars with rope wraps or oar sleeves can sometimes fit snugly in oarlocks. Call 866-539-9323 to talk to one of our experts about fit.
