In order to cut full size sheet goods I must open my garage door, I only have 6' from front of saw to door. With my old door, when open, I only had 7' of headroom. Catch 22. Well, my problems have been solved. Got this door put in over the weekend with a high lift kit. Now I have all the headroom I will ever need. Opted for two light panels also b/c you can never have enough light. Thanks for looking, posted more shop pics in album.
