Who it's for

What we like

  • UL Group 2 listed, 1 million possible combinations, all-metal wheels (S&G)
  • No battery or electronics to fail
  • Four-way drive cam for universal mounting (S&G)

What to know first

  • Slow to dial and hard to read without a light
  • Changing the combination means the key-changeable wheels behind the back cover, a job dealers leave to a technician
