Has an overall outside opening of 73"x24". This door is in pretty rough shape, this aluminum entry door for Spartan trailers but has been painted silver. It does have the window glass and the original window seal. It is missing the outside and inside lock assemblies. It has holes under the foil tape from where a hasp once was screwed on. We do have a retrofit kit (outside only part# CHW097) available on our e-store to replace broken exterior locks like these..
To tell if you have a left or right hand door, look at the door from the outside and whichever side the hinge is on that is the type of door you have.
