Carabiners play an important role in any climber’s gear assortment. To enhance your safety, be sure to keep them regularly inspected and maintained.
● Check all surfaces regularly for cracks, sharp edges, corrosion, burrs or excessive wear. Even hairline cracks can reduce 'biner strength significantly.
● Make sure no rivets are bent or missing.
● Check each gate to make sure it opens and closes quickly and easily. Be sure all gates (and any locking mechanisms) close freely and completely. If the gate does not function properly, or if it's askew or bent, retire the 'biner.
● Carabiners that have been dropped a significant distance should also be retired. Dropped 'biners can suffer significant damage yet still appear intact. When in doubt, do not use it.
● Clean gates by blowing dust and dirt from the hinge area.
● If you notice a sticky gate, wash it in warm, soapy water (citrus-based bike cleaners also work well), rinse it thoroughly and let it dry.
● Lubricate it with dry graphite or any dry, waxed-based lubricant around the hinge area, the spring hole and the locking mechanism. Be sure to wipe off all excess lubricant.
● Always clean and lube your carabiners after contact with saltwater or salt air.
● Keep your carabiners free from burrs that can damage a rope.
● To sand down burrs, use 220-400 grade sandpaper. If this doesn't remove the burr, destroy the carabiner.
● Do not file carabiners for any reason.
● Do not store your carabiners in humid or salty air, with damp equipment or clothing, or near corrosive chemicals.
