Why a drive-through conex?

A regular container only opens at one end, so whatever goes in first ends up buried. Put a roll-up garage door on each end and it becomes a steel garage you drive straight through.

Who it's for

  • Contractors and landscapers: mowers, compactors, attachments and hand tools, locked up and easy to roll out.
  • Ranches and farms: UTV, ATV, small tractor, fencing and feed, out of the wind and snow.
  • Horse property: tack, hay and the side-by-side by the barn. Open both ends for air.
  • Acreage and homeowners: mower, snowblower, boat, toys. The garage you don't have.
  • Small business storage: stock goes in one end and comes out the other.
  • Workshops: open it up for light and air while you work, then close it and lock it at night.

Straight talk on roll-up doors

  • They're far easier to open every day than the original cargo doors, and they need no swing room.
  • Each door locks with a padlock hasp. Lockboxes are available.
  • They aren't as tight as cargo doors. In a hard, driving rain a little water can run down the tracks. Set the box with a slight slope to one end, or keep the cargo doors on one end.
