  • With magnetic arms in the gate and a steel insert in the nose rather than a twistlock or screwlock, the Magnetron 'biner is simple to operate and totally secure
  • Both magnetic arms must be individually depressed before the gate can open, to prevent accidental openings
  • Once open, opposing magnetic fields repel the arms to ensure smooth and reliable gate operation
  • Symmetric design lets you open the gate easily with just 1 hand, either your right or left
  • GridLock design features an extension at the bottom of the gate to keep the 'biner properly oriented on your belay loop to avoid cross loading
  • I-beam spine transitions into a rounded rope-bearing surface for smooth belaying and rappelling
  • Hot-forging process allows the metal to be moved around and formed into intricate shapes; these shapes can ease handling and reduce weight
  • Black Diamond Magnetron GridLock Belay locking carabiner has a key lock nose that won't snag on pro, ropes or slings, making the 'biner simple to clip
  • Magnetic arms on the gate come in assorted colors only; sorry, specific color requests cannot be accommodated
