How to Use a Grappling Hook

A grappling hook is a multi-pronged metal hook that attaches to a length of rope through a center eyelet. The grappling hook found its first use in naval combat, by sailors boarding enemy ships to engage in battle. Today, the grappling hook is still used by military units and, just as often, by mountaineers who need to climb a difficult ledge. Follow these steps to use a grappling hook.

Instructions

Difficulty: Moderately Challenging

1. Make sure your gear is ready. You need to have the right hook and rope to use a grappling hook safely. Keep in mind that you will be putting the full load of your body on both the hook and rope. The hook should be specially designed for grappling. Black Diamond makes climbing quality hooks that are designed to grab a ledge and hold it. The rope should be undamaged and rated to support at least triple your body weight.
2. Identify the ledge to grab. This is the most important element in the correct use of a grappling hook. The ledge needs to be distinct, clear of obstructions and solid. In most cases, you will have to use visual cues to determine if the ledge is good enough to use for grappling. Look for cracks, discoloration and fallen stone below it to make the right decision.
3. Take a wide swing. To launch the grappling hook, use a wide, underhand swing. Hold the grappling hook's rope about one foot away from the hook. Let the hook dangle by your shins. Place one foot towards the ledge and the other away, so you're standing sideways to the wall. Then in one large motion, swing the hook from your back foot so that you launch it in a large arc.
4. Test the hook's grip. Before you start climbing you need to make sure that the grappling hook has a good grip on the ledge. Unlike ninja movies that show characters giving two quick yanks on the rope, you need to put your full body weight on the rope and hang from the hook just slightly above the ground. Try to hear or feel for any movement whatsoever from the hook. If the hook is securely in place, then start climbing. If there is movement, work to dislodge the hook and try again.
