Technical Data

Lock & Key Technology

  • Each side of the lock has 5 sprung, solid tumblers, arranged axially.
  • Comprises of 10 sectionally arranged core and housing pins.
  • Solid pin tumblers with a minimum diameter of 3mm, made from tempered bronze/steel, hardened and chemically nickled.
  • Smallest locking unit across the pin tumblers, solid pin with a minimum height of 0.8mm.
  • Waisted core and housing pins.
  • Up to 12 positively fed, solid revision pins, arranged vertically and horizontally on two levels.
  • One-piece cylinder housing made from solid brass, surface treated with several galvanised layers, high protection against corrosion.
  • Cylinder core made from solid brass, one-piece, with a minimum diameter of 13 mm.
  • Core with horizontal basic profile which protects the sides of the truncated cone pin heads to optimise locking security.
  • Concave core head as an aid to inserting the key.
