If the building is less than 60' wide design using the Attic Heads by Tyco, Viking or Reliable (70' wide) Back to Back heads down the Ridge line. Regards, G. Tim Stone G.

I'm picturing perpendicular to mean "across" the joist, not up the slope, correct? Also, the min. 5'-0" dimension from the eave is kinda goofy, if I come in 5' from each eave at a corner it puts the head right on the Hip. I only do about (1) wood framed job a year so each time it's like starting over, any pointers from you attic experts? And unfortunately the roof span is too wide to use attic heads....
