Often our customers have difficulty choosing between our two cabinet lines, Heavy Duty and Challenger. Both frame lines feature:

  • all welded construction
  • movable panel mounting angles for flexibility in mounting equipment
  • positive door latching (not Velcro or magnetic stripping)
  • wide variety of accessories
  • manufactured under an ISO 9001 compliant quality program!

Corner Samples

The corner details show the differences in frame construction. The Heavy Duty frame features double ledge, double plane plane corner construction making it incredibly strong. It’s capable of supporting up to 3000 lbs of equipment. The Challenger line is designed for less strenuous duty. It’s supports approximately 800 pounds.
