Preventative Maintenance

Your hangar door is an investment and you want that investment to last.  To ensure trouble free service, your door should be inspected and maintained on a regular basis.  This maintenance can include, but is not limited to: 

  • Checking lift cables, cable guards and lock cables for damage 
  • Ensuring any hinges, the drive chain and gears are all properly lubricated
  • Checking seals for cracks or breaks
  • Making sure any rollers are free turning
