Thread: Box trailer weather tight door seal design - help required

I drove a nissan truck with 6m box body with gull wing doors... if you make the first say 200mm of box ridgid that makes life much easier as you can pull down tight the moving bit... it had simple hook and cam over latch,one at each end of door... it actually had another in centre being such a long span. pretty much any soft squishy type of rubber seal will work if you can pull the top/outer bit down firmly.
