DMM Shadow Carabiner, Matt Gray

The DMM Shadow carabiner in matt gray is an aluminum auto-locking carabiner with a keylock nose that does not snag on rope or slings. The matt gray finish has a low-glare, understated look that many climbers like.

Where the Shadow fits

The Shadow is a general-purpose connector for arborist work: lanyard ends, connecting devices and clipping to saddle attachment points. The keylock nose runs smoothly through rope eyes and sling loops without hooking, which saves frustration when you are clipping in one-handed.

The matt gray finish is about looks, not performance. It is the same Shadow, just in a muted color. Compare other auto-locking carabiners if you need a different shape or gate.

Some climbers use color to organize their saddle, with one color for the climbing system and another for lanyards or spare connectors. A matt gray carabiner stands out from the bright anodized colors many arborist connectors come in, so it is easy to set aside for one job. It also shows fewer scuffs from bark and grit than a glossy finish. Whatever system you use, keep it consistent so you can find the right carabiner by feel and sight while working aloft.

Use and inspection

Load it along the spine with the gate closed and locked. Before each climb, check that the gate snaps shut and locks on its own, and look for grooves, cracks, sharp edges and corrosion. Retire it after a big fall or a drop onto a hard surface.

Life-support gear must meet the applicable standard, be used per the manufacturer's instructions and ANSI Z133, and be inspected before every climb. Get trained before you rely on it aloft.
