Four Fold with Catenary Notch and Monorail Notch

Do you need transportation doors that are:

  • Long lasting?
  • Low maintenance?
  • Highly energy efficient?
  • Abuse resistant?

Depend on a specialized Hydraulic Four Fold door. The Hydraulic Four Fold Door has an area at the center opening that is perfect to notch for the catenary to go through. A common problem for roll-up doors, the Four Fold Door perfectly folds around the catenary. There are no floor guides, so the door easily glides above the rails.
