In rafting, carabiners (aka “biners”) are used in rope and pulley rescue systems, to secure things to a raft and as items of adornment in river guide apparel. The Locking D Carabiner is a great choice because the rope rests closer to the straight section rather than being near the gate, which makes it inherently stronger. The locking gate keeps your rope inside the carabiner without the worry of it accidentally coming loose at the wrong time. Never go to the river without having several!
