This stair frame is attached to the trailer floor with hinges and pulls up inside the door, with a simple rope, so the exterior door can close to maintain weather tightness. The treads are 4 feet wide (which can be made to any width) and is a easy step pattern to climb up and down. All aluminum construction with stainless hinges. One hand rail allows room to hand up or down equipment.
