Inclosure 1 is the detail for the mono vault truss. In­ closures 2 and 3 are the design values for the plywood Eind nails used for that detail. Inclosure U is the detail for correcting the bearing area shortfall for trusses "UG" 4 "U2". Inclosure 546 are de­ sign values for lumber and fasteners, respectively. Should further questions arise, please feel free to contact our offices.
