Hello! Here are some dimensions:
Here is the material from a previous post in this forum from another member that they posted.
Total Height = 51 1/4" (including 1/4" felt pads on the feet)
Total Width = 10"
Rung Width = 7"
Sides = 1 1/2" x 1 1/2" square fir (labelled as 2x2 though...but it's not!)
Rungs = 1" Hardwood round dowel
First Rung = 21 1/4" from floor
Second Rung = 31 1/4" from floor
Third Rung = 41 1/4" from floor
Use a 1" forstner bit to drill your holes, can do 1" depth into each side. Very strong!
Also, round over your outside top corner.
Check your height. It may differ slightly from trailer to trailer. I kept the top flush with the top edge to help avoid any clothing snags or injuries.
All purchased from home depot in the trim/moulding section.
Hope this helps! Cheers! JMR
