Ripley, Ontario Canada | The default here is 4 foot spacing with 2x4 on flat on 2 foot centers up the roof. There has been a big change in the bracing though. My shed built in 1970 has 1 2x4 down the center of the bottom chord, the piece I put on the barn in 03 required a 2x4 every 6 feet on the bottom chord, a 2x4 on every web in the truss, and the builder said if the web was more than 6 feet long put 2 2x4 on that web, plus angle bracing on each run of 2x4 in the webs. | |
