Increases Safety

  • Rolls upward and stays in position until pulled down
  • Door will not close or free fall on its own
  • Eliminates risk associated with swing-out doors on curbside or roadside
  • Constructed of strong, double-sided aluminum extrusions
  • Incorporates a stainless steel bar lock

Even though the primary focus for these doors is the exterior of a work truck, they can be used for many special applications such as for food trucks, counter shutters, pit carts, pull behind trailers, RV's and just about anything you can imagine inside or outside.

Please Note: This door extends into the cargo area approximately 10" at the top of the door and coils onto a drum. This is more critical when the door is mounted lower as it will protrude into the vehicle and may be in the way of cargo.
