Thanks- I was thinking of something like this- I was mainly trying to keep a rail up there to keep from pushing things off the side when storing big items. I have forks for my tractor so I was going to leave an opening for that as well.I left a big opening so that I could fork heavy stuff and pallets. For the handrail I kept in mind that this was not a space that was "open" to the public and kept it to a minimum, not in strength but as far as code. Basically just a top rail screwed to several 2x4s lagged to the face of the band board so that if I decided to actually build a wall to the ceiling in the future.
Code would have something ridiculous like no more than a 3" opening all the way across.
