The body is die-forged from 7075 aerospace aluminium, the same grade used on real climbing hardware. One-piece forging keeps the grain unbroken, so the D-shape takes a 25KN rated pull without flexing. Each rock climbing lock is laser-marked with its strength data on the spine.

The screw-gate closes with a threaded nut that spins smooth and never slips. A knurled band gives your fingers grip even with gloves on, and the gate keeps its tension after hundreds of open-and-close cycles. Mud and grit rinse out of the thread with plain water.

Five anodized finishes cover every brand palette: lake blue, rose gold, dark green, matte black and bronze orange. The anodic layer is sealed, so the color resists sweat, rain and abrasion, and it will not flake the way paint does.

Each rock climbing lock arrives ready to clip. The screw gate is cycled and checked before packing, so the thread runs smooth from the first turn, and the spine marking faces out when the gate hangs closed.
